Moving from ESXi to Proxmox

≫ Next: web interface not working?

≪ Previous: add interface veth in CT VM

Hi guys,

I have been using ESXi for a few years now in my home to host a Few Windows OS's, PFSense and FreePBX.

I have a few questions before I take the plunge and dig deeper into Proxmox.

My setup consists of a HP ML110 (Not powerfull but suits my needs for speed, power draw and noise)
It has 3 NIC's. 1 Onboard and a Dual Intel PCI-E NIC. - The Onboard NIC is used as the general NIC for the VM's and Monitoring. The Intel Dual NIC is dedicated to LAN/WAN use by PFSense, The WAN adaptor also has vlan tagging ID of 10 set to the interface.

I am experiencing poor disk performance due to no cached disk controller with the current ESXi software.

I am a GUI oriented guy but will dig into the command line if required by following documentation or suggestions of others but not very knowledgable in this regard.

I guess it all boils down to: Can I easily duplicate my NIC setup as above in the Proxmox GUI?
What is performance like without a cached disk controller? I know I can use Hyper-V to increase this performance... But would Prefer Proxmox.
Are there any issues with the OS's above that I should be aware of? Windows Server 2012 R2, FreePBX and PFSense.

Regards

When he left he never mentioned about the proxmox ve server and or how to get on it, he FINALLY gave up the password, but i can't access it. Any help would be appreciated because i need to increase the hard drive on the data base very soon, i took over this postion with little or no help from him.

Help with re-installing Grub on my Proxmox 3.4

March 31, 2015, 5:20 pm

≫ Next: Windows QEmu Guest Agent...

≪ Previous: web interface not working?

Hello,

I upgraded my Proxmox from 3.1 to 3.4. During the upgrade I was asked to re-install grub and pick one. Stupid me didn't and said no. Then when I rebooted my Proxmox is now broken most likely due to Grub.

So I've loaded up through my IPMI the Proxmox 3.2 .iso and I've been able to get to the console (after error CTRL-D). I'm at the command line and I've figured out where grub files are (/mnt/usr/sbin/). I've been searching the forums for an answer.

This wiki says I can use the debugging from the Proxmox .iso (which I've now got into). But it doesn't say How to fix Grub? - http://pve.proxmox.com/wiki/Debugging_Installation

This post says to use upgrade-from-grub-legacy - http://forum.proxmox.com/threads/917...2057#post52057. I get an error that upgrade-from-grub-legacy cannot be found (yet I do see it in the /mnt/usr/sbin folder).

This looked promising but using update-grub and grub-install both come back wtih errors in line 3: gub-mkconfig: not found - http://ahmet.tekelioglu.org/en/rescu...grub-breakdown

This post suggested I use Boot Repair Disk. http://forum.proxmox.com/threads/165...t-GRUB-failure. So I downloaded boot repair disk and loaded it up in my ipmi and I've booted into it. It found my boot partition which is promising...but it needs internet to finish? How do I connect Internet from the LiveCD?

I'm beginning to think using the Proxmox .iso is not the way to fix this?

Any ideas please on what the proper steps are to re-install/fix grub on Proxmox 3.4?

Thank you,

How I fixed: Grub2 fails on fresh install (incase anyone else has this issue)

March 31, 2015, 9:00 pm

≫ Next: Memory Baloon in action.

≪ Previous: Windows QEmu Guest Agent...

So I just spent the last 12 hours going through installing proxmox 3.4. Everytime I try the bootloader is broken. I found a work around using super grub2 or systemrescue cd by doing the following.

Setup: asus-u47a core i7 laptop with a single 750G hdd.
Nothing... just used imageUSB like the wiki says and put the 3.4 iso on the usb and booted. I disabled uefi in my bios during install, since booting via uefi booted to "grub rescue>".
The only thing I changed during the install was the domain (to proxmox.local)

After installation completed, I put in a copy of system rescue cd (imaged to usb by unetbootin), changed the bios back to uefi boot=enabled and booted the rescue disk in uefi mode. If you get a black grub type screen with white text, you did it right. If you got the blue unetbootin screen, your not using uefi mode. (the blue screen might work, but after 12+ installs today I don't feel like another, try and post the results).

In the grub for system rescue cd, select "Boot an existing linux system installed on the disk". (if you got the blue unetbootin screen and super grub2 is an option near the bottom, select that, select enable extra grub2 functionality, enable lvm (and raid if you use it), go back a menu, select detect any grub2 configuration file (grub.cfg), it should find (lvm/pve-root) select that and it should boot).

This will boot proxmox. login to proxmox as root.

run:

Code:

mount /dev/sda2 /mnt

cd /mnt

ls

If you don't see an EFI directory as the only directory in /mnt, you mounted the wrong partition, do "umount /mnt" and try again with another partition, we're looking for the one with the EFI folder.

When you find it and have it mounted at /mnt run the following:

Code:

grub-install --efi-directory=/mnt

That's it. no need to specify /dev/sdx. Reboot and enjoy.

If anyone's having trouble with this maybe I'll make a video or take some screen shots tomorrow if I remember.

Good luck.
Dont-panic.

Guys

Are there any way to see memory ballooning in action?
I have multiple guests which are not using memory fully and for sure host can steel certain amount of memory from them instead of using swap.

Memory Balloon is not much documented in Wiki.
Requirements are not clear. For linux it is mentioned that nothing is required.
But then how to see I have everything required on host and guest.
And see ballooning in actions at all.

Thank you very much.

spoof eth0 under bridge

April 1, 2015, 1:50 am

≫ Next: TASK ERROR: can't activate LV : Unable to resume Resume (253:4)

≪ Previous: dlm: disagrees about version of symbol module_layout

Hey,

I'm looking for a "reboot" stable configuration. I want to spoof (permanently) the mac address of eth0 that is allocated for bridge (vmbr0). I first attempted to change the mac addr for vmbr0 but that is not working. (or atleast not as intended)
After a bit of reading, it seems that a bridge needs a "valid mac address" of a device (beeing eth0 here).

So I need to change the eth0 mac address, now I figured out how I could achieve this using :

Code:

ifconfig eth0 hw ether 00:11:22:33:44:55

This results in : (ip addr)

Code:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

    link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff

9: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN

    link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff

    inet 111.111.111.111/16 brd 111.111.255.255 scope global vmbr0

    inet6 fe80::21a:8cff:fe22:6d8/64 scope link

       valid_lft forever preferred_lft forever

However I'm pretty sure it won't survive a reboot; I assume /etc/network/interfaces is the right place to look; however eth0 is not defined there

Code:

 cat /etc/network/interfacesauto lo

iface lo inet loopback





auto vmbr0

iface vmbr0 inet static

        address ***

        netmask 255.255.0.0

        gateway ***

        bridge_ports eth0

        bridge_stp off

        bridge_fd 0

So how can I define eth0 or where is it defined so I can make this adaptation survive reboot.

ps. I changed the values of mac & IP

≫ Next: manually alter ram and cpu sockets or core? balloon setting?

≪ Previous: [Proxmox 3.4] Start KVM guest qcow2 image from ZFS store

Hi there
We have now installed Proxmox VE 3.4 with ZFS RAID-1 on more than 6 servers with 2 disks each (attached to LSI 9207-8i HBAs), without any issues.
On several other servers with 4 disks and ZFS RAID-10 we are experiencing the same issue as described under http://pve.proxmox.com/wiki/ZFS#Grub_boot_ZFS_problem :

Symptoms: stuck at boot with an blinking prompt
Reason: If you ZFS raid it could happen that your mainboard does not initial all your disks correctly and Grub will wait for all RAID disk members - and fails. It can happen with more than 2 disks in ZFS RAID configuration - we saw this on some boards with ZFS RAID-0/RAID-10

I have managed to boot the servers by changing the boot drive in BIOS (after trying to fix Grub2 via Proxmox VE Installer rescue mode first...). With some luck, you will get the correct drive and will be able to boot.
Here's the problem: Proxmox VE 3.4 Installer does not seem to partition all disks correctly on a 4 (and possibly more) disk setup, ZFS RAID-10:

Code:

In this example, /dev/sdb and /dev/sdc are missing the Grub-Boot and EFI partitions. Writing Grub to those disks will not succeed:

Code:

$ grub-install /dev/sda

Installing for i386-pc platform.

Installation finished. No error reported.



$ grub-install /dev/sdb

Installing for i386-pc platform.

grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.

grub-install: error: filesystem 'zfs' doesn't support blocklists.



$ grub-install /dev/sdd

Installing for i386-pc platform.

Installation finished. No error reported.

This is a serious issue. You would be able to run a server in production in this condition but not having Grub installed on all drives is quite risky!
Please fix or explain why this happened. Thanks.

at the new location i cannot get kvm's to run, either from a backup (from the working location) or, if i create a new kvm. creating a new kvm goes fine until i reboot or power cycle the kvm. in all instances the message i see in the proxmox web gui is 'internal-error' after a few seconds of starting. i've tried to start the kvm by disable 'kvm hardware virtualization' and when i deselect that the kvm will start, but the windows boot says that the volume is damaged, or, i see only a black screen.

so, whether i use a backup and restore and try to start, or, if i create a new kvm from scratch, on start i see always 'internal-error' and i can duplicate it every time.

here is my pveversion output
proxmox-ve-2.6.32: 3.4-150 (running kernel: 2.6.32-37-pve)
pve-manager: 3.4-3 (running version: 3.4-3/2fc72fee)

the server is 48gb ram and quadcore xeon 5520. it has also a lsi raid 5 hardware.

if there is any ideas about this i would appreciate it. i already worked it two days without any good results.

PROXMOX VE , can we segment servers if some are in another directly connected network

Hi guys

Can we have a PROXMOX host management server control seperate OS instances/virtual machines if these servers are in two different directly connected networks , so if the server is in one network can it reach the other network and can it still segment the VM on remote servers ?

We want to start using PROXMOX VE on our new to design network.
But we before we make the seperation of the two networks we want to know if this is possible.

Inside proxmox we want to us only KVM. (without the use of containers with OpenVZ)
Most of our virtual machines run linux distro debian ... also the proxmox hosts are installed on Debian.

1) We want to create two networks , Each network will have 2x WS-C4900M core routers/switches.
2) Each core is connected to two Cisco Nexus Parent switches (N5020)
3) Each N5k-C5020 is connected to 4 to 2 racks in which we have 2 Nexus extenders (connected to the parent switches with SFP+), we talk about 10-15 servers per rack ,so each server connected to each extender in the rack (redundancy purpose).

I have read about Open vSwitch a virtual multilayer switch .. which works with PROXMOX and gets installed on the debian distro's, does this do the trick ?

Open vSwitch :
Open vSwitch is designed to support transparent distribution across multiple physical servers by enabling creation of cross-server switches in a way that abstracts out the underlying server architecture, similarly to the VMware vNetwork distributed vswitch or Cisco Nexus 1000V.

Open vSwitch can operate both as a software-based switch running within the virtual machine (VM) hypervisors, and as the control stack for dedicated switching hardware; as a result, it has been ported to multiple virtualization platforms and switching chipsets. Open vSwitch is the default switch in XenServer since its version 6.0 and in the Xen Cloud Platform (via its XAPI management toolstack); it also supports Xen, Linux KVM, Proxmox VE and VirtualBox. Open vSwitch has also been integrated into various cloud computing software platforms and virtualization management systems, including OpenStack, openQRM, OpenNebula and oVirt.

Linux kernel's implementation of Open vSwitch was merged into the Linux kernel mainline in kernel version 3.3, which was released on March 18, 2012, official Linux packages are available for Debian, Fedora and Ubuntu.

As of November 2013, Open vSwitch provides the following features:
Exposed communication between virtual machines, via NetFlow, sFlow, IPFIX, SPAN, RSPAN, and mirrors tunneled via Generic Routing Encapsulation (GRE)
Link aggregation through the Link Aggregation Control Protocol (LACP, IEEE 802.1AX-2008) LACP is used for creation of a port channel, the extender and parent support port-channel but also this open vSwitch support it when needed.
Standard 802.1Q Virtual LAN (VLAN) model for network partitioning, with support for trunking
Support for the Bidirectional Forwarding Detection (BFD) and 802.1ag link monitoring
Support for the Spanning Tree Protocol (STP, IEEE 802.1D-1998)
Fine-grained quality of service (QoS) control for different applications, users, or data flows
Support for the Hierarchical fair-service curve (HFSC) queuing discipline (qdisc)
Traffic policing at the level of virtual machine interface
Network interface controller (NIC) bonding, with load balancing by source MAC addresses, active backups, and layer 4 hashing
Support for the OpenFlow protocol, including various virtualization-related extensions
Complete IPv6 (Internet Protocol version 6) support
Support for multiple tunneling protocols: GRE, Virtual Extensible LAN (VXLAN), Internet Protocol Security (IPsec), GRE, and VXLAN over IPsec
Remote configuration protocol, with existing bindings for the C and Python programming languages
Implementation of the packet forwarding engine in kernel space or user space, allowing additional flexibility
Multi-table forwarding pipeline with a flow-caching engine
Forwarding layer abstraction, making it easier to port Open vSwitch to new software and hardware platforms

Thanks for any suggestion.

Hi,This is my first post, so please be kind if the post is not placed in the right location.My home gateway / vivid wireless "4G" account is a few years old, but it seems that the speed is getting slow more often, which is quite frustrating.Looking on the forum, it is recommended to have a look at RSSI and CINR parameters, so I tried to logon to 192.168.I.I as recommended, but got a fail -1 error when entering logon details.I followed The instructions of 192.168.l.l | 192.168.1.1 Can you please help?Thanks.
