I am going to install emulex Lpe 1250 8gb pci-e hba card on proxmox ve 3.3.
I am newbie to proxmox and fc hba card, and I am a little confused about this installation.
1. Is emulex hba card out of box?
2. where can I get the driver for emulex hba card?
3. where can I get the fc multipath software?
4. Is the wiki page http://pve.proxmox.com/wiki/ISCSI_Multipath suitable for fc multipath configruation?

qm clone gives unable to parse volume ID

I tried to clone a vm with the command line, by
qm clone 101 103 -name WebServerNew -format raw -full 1
but got "unable to parse volume ID '/dev/disk/by-id/scsi-SATA_WDC_WD40EFRX-68_WD-WCC4EHJF6HLX-part1'"

This partition is a raw mapping into my virtual machine:
virtio7: /dev/disk/by-id/scsi-SATA_WDC_WD40EFRX-68_WD-WCC4EHJF6HLX-part1,backup=no

It seems the regular expression in /usr/share/perl5/PVE/Storage/Plugin.pm:185 does not support this.
a) Is this a bug?
b) If no, what is the preferred way to do such a raw mapping?

OVH failover Ip + proxmox windows guest

Greetings everybody,

The last couple of days I've been trying to look for a nice virtualization panel / system, and proxmox is what I ended up with and what I'm happy with.
However, I installed it on a clean Debian installation using the following guide:
https://pve.proxmox.com/wiki/Install..._Debian_Wheezy

The VM is running just fine and all, except for the network part. I've been strugling with this network issue for days now and checked out many guides / info ( from this forum aswell ), but couldn't seem to make it work.
tcpdump shows I'm pinging to an outside domain using the virtual machine ( google.nl, NIC=VMBR0 ):
Code:
94.23.xx.xx > ea-in-f94.1e100.net: ICMP echo request, id 1, seq 14, length 40
However, this always times out.
The DNS does not seem to work neither as I cannot simply ping to google.nl.

My host /etc/network/interfaces:
Code:
auto eth0
iface eth0 inet static
address 37.187.xx.xx
netmask 255.255.255.0
network 37.187.74.0
broadcast 37.187.74.255
gateway 37.187.74.254
pointopoint 37.187.74.254


auto vmbr0
iface vmbr0 inet static
address 37.187.xx.xx
netmask 255.255.255.255
bridge_ports none
bridge_stp off
bridge_fd 0
up ip route add 94.23.xx.xx dev vmbr0
Settings on Windows server 2008 guest:
Code:
IPV4:
 - IP Address: 94.23.xx.xx
 - Subnet mask: 255.255.255.255
 - Gateway: 37.187.74.254
IPV6:  disabled
I tried the host address as the gateway aswell, but didn't work.
Using the failover ip with .254 does not work neither.

The vm has a E1000 network adapter with the mac address I received as "Virtual MAC" from ovh.

Could perhaps somebody assist me?

How to create a TigerVNC auto-login shortcut in Windows

October 24, 2014, 9:14 am

Hi,

I've followed the instructions on the Wiki to gain access to my VM via TigerVNC, & it works properly from Windows 7.

Now I'd like to configure the client to automatically connect to the console when I launch it from a shortcut.

First I tried saving the connection from the TigerVNC client window into a .tigervnc file, but it wouldn't launch, giving a 'host not found' error although I could connect through the client connect dialog with the same settings.

I'm able to connect via a standard Windows shortcut, using the following command (Where 'x' is the IP, & 'y' is the port):

Code:
"C:\Program Files (x86)\TigerVNC\vncviewer.exe" x.x.x.x:yyyyy
But every time I connect via this method I have to first click 'Yes' to a dialog which asks:
"Hostname (x.x.x.x) does not match any certificate, do you want to continue?"

Then I have to log in & type "root@pam" & the password before it'll finally bring up a screen.


I can't seem to find any information on how to completely automate this process so that all I have to do to get a local screen is click the shortcut icon.

Does anyone here know how?


Thanks in advance,
-J

Guest disk data security

Hello,

Please consider extending virtual disk add/remove (extend may be difficult) functions to wipe (de)allocated space before it's visible to other guests.

We've send similar idea to LVM mailing list

http://www.redhat.com/archives/linux.../msg00018.html

but more general solution (compatible with other storage backends) would be better for PVE probably. OpenStack seems to have some solutions for this problem:

Thank you for great tool!

Hello!
I am attempting to setup a virtual network for a subset of VMs to communicate on, i.e. completely virtual LAN.
I have tried the following:
1. edited /etc/network/interfaces to ...
auto vmbr200
iface vmbr200 inet static
address 10.10.10.0
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0
2. then i ran ifup vmbr200 on the host
3. added another NIC to the VM attached to vmbr200
4. open VM, run ifconfig ... no 10.* network shows up...

What am I missing?

Thanks!

Infiniband: storage options

October 25, 2014, 6:12 am
$

Storage array: Omnios with zpools
Infiniband: Voltaire dual-port infiniband HCA PCIe 500Ex-D (DDR)
Switch: No. Direct connected
Subnet manager: opensm running on proxmox nodes (gives fail-over since second opensm will automatically start in passive mode)
Proxmox: 2 nodes 3.3 with Qdisk on separate shared storage

What is the best way to implement storage for proxmox over infiniband?
IBoIP: This should be straight forward and will involve using the ZFS plugin. Live migration, storage migration, cloning, and snapshots
SRP: LVM groups with network backing. Live migration and storage migration but no cloning and snapshots
iSER: LVM groups with network backing. Live migration and storage migration but no cloning and snapshots

IBoIP
pro:
  • Complete storage support
  • Flexible

con:
  • Lower performance
  • Less mature in proxmox but running stable here for 1.5 years


SRP and iSER
pro:
  • Higher performance
  • Mature in proxmox

con:
  • Lacks cloning and snapshot feature
  • Less flexible


Benchmarks available via google shows IBoIP in connected mode with mtu 64k can easily saturate infiniband DDR so I guess for DDR the performance issue is less of a deal breaker.

So summing it all up I should mean when storage array is ZFS the best option would be IBoIP since this gives the full featured proxmox storage model.

What do you think?

(PVE from ISO 3.3 / Kernel 3.10.0-4-pve / OVS 2.3.0-1 )

Hi,

During the boot process I can see (unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory) everytime OVS try to do an action, it is like networking process is starting after it. To double check, after booting and doing a /etc/init.d/networking restart everyting is allright and my OVS is running well with all I set on /etc/network/interfaces.

I checked and the OVS 3.3 is patched so I don't know what can still avoid OVS to start properly?

Many thanks,

Failing backup job

October 25, 2014, 5:04 pm
$

Now and then a thread pops up where someone has problems with a backup job were backups of some of the VMs fails. I have investigated this problem and I might have found the cause for this problem.

The problems boils down to two specific issues:
  1. Limited IO in either the backup storage or the network
  2. The configured backup job contains VMs from more than one Proxmox node


Why is the above issues a problem?
The problem is that the backup job only serializes backups on one Proxmox node which means that if your backup job contains VMs from more than one node the backup job will start a backup from the backup list on each Proxmox node in parallel. Expressed mathematically f(x) = n * b(p); n = Proxmox nodes; b = backup from node p.

How can I overcome this problem?
To prevent running parallel backups create a backup job for each Proxmox node and ensure the backup job only contains VMs which runs on the same proxmox node.

Is this bullet proof?
Yes and no.
Yes: If you always backup every VMs then it is bullet proof if you use selection mode: all
No: If you only want to backup running VMs then you will have a problem since over time the list of running VMs on a given Proxmox node will eventually change due to migration, new VMs can be added, VMs can be removed, VMs can be stopped so this lists needs to be overlooked on a daily basis.

How can this limitation be solved?
Add a new selection mode called running which well select all VMs on the configured node with status running.

How do I fix this, the Virtual Server was working before?
I try to start the container and error:

I try to view the container from the Proxmox console.
Can I find what the cause is, or do I have to reinstall the virtual server and the program to run on the virtual server host?

Ok, I think it was my Memory allocation of 1024MB.
I reduced the Memory to 32MB and the container sort of started.
The container went to the Ubuntu server install, however I have already installed and configured a program, so something's gone wrong.
Also, the container's install won't respond to me pressing the keyboard?

Anyways, question now is, how do I calculate how much memory can be allocated to Proxmox containers?
If the computer with proxmox has a 2GB memory stick
then container 1 could have 1 GB memory
container 2 could have 1 GB memory
container 3 and 4 could have 0 memory.

How do I check how much memory Proxmox reads on the memory stick on the computer? Is there a command?
Can I then read the allocated container memory that I set and add them up?

Dear,

config-files under /etc/pve cant been bigger as 130.000 bytes! This is a big big problem, for the firewall blacklist!
We will block in this datas of many IPs wich more as 256 kBytes.

So, my questions are:

Is that possible to include a file in the blacklist from other directory, expl in the cluster.fw

Code:
[OPTIONS]


enable: 1
policy_in: ACCEPT


[ALIASES]


// small entries


[IPSET blacklist] # gesperrte IPs

include(/root/ext_blacklist.txt)
OR how is possible to change, that files can been written more as 130.000 bytes?

I am running Proxmox 3.3 on a 120G drive, and have a 250G software raid1 setup as storage for all the VMs. The problem is that Proxmox only registers the raid as 23.7G, and will cause the VMs to "run out" of storage when that space is filled. When I run a df -h on the server it comes up as the full sized raid. Has anybody had this problem before, or know of a way for me to fix it?

Hello,

i would like to make a little poll for the backupformat what is in use. For the last years i always used gzip. Works, but not really fast. Since the last few weeks we changed to lzo, an the speedup was amazing. So what format is used from others, and is LZO really stable... it es the default in Proxmox right...
