GUI not in sync with reality

October 2, 2014, 11:12 am
$

I've got a situation right now where one VM, upon reboot, encountered filesystem corruption.
Upon closer examination, I see that the Proxmox GUI doesn't accurately reflect which cluster node that VM is running on.
The GUI shows VM #107 running on node #2, whereas the KVM process with -id 107 is actually running on node #4, and is not present on node #2.
clustat(8) correctly indicates that the VM is running on node #4.

What could cause the GUI to get out of sync, how do I fix it, and where would I look (i.e. what log file) for indications of what went wrong?

New install uses eth0 port not eth2, on correction: web access "connection was reset"

I have done a fresh install of Proxmox PVE on a machine and when the installation is complete, after restarting, eth0 is used to set up the bridge. In fact eth2 (eth0-3 exist) is the correct cabled port.

So by changing the port to eth0 in /etc/network/interfaces, the network access is activated. I can ssh into the machine. However attempting to access http://192.168.121.123:8006 results in a certificate warning and after accepting the exception, I get a page that says: "The connection was reset".

On the server:

Hello I am trying to add UFS support to the pve kernel and after I install the kernel headers change the kernel to have UFS support I try to compile it but it does exit with the following error:

make[3]: *** No rule to make target `kernel/bounds.c', needed by `kernel/bounds.s'. Stop.
make[2]: *** [prepare0] Error 2

This seam to not have the full kernel source. Is there a way I can get the kernel source to be able to finish my task?

access noVNC html5 console from external site / vncwebsocket via api?

Hi,

I have an (password protected, of course) external site which allows to access any VM console through the proxmox PVE-API by utilizing vncproxy command and loading the Java console applet.

I would like to update this site to the new noVNC html5 console as it is included in Proxmox 3.3.
Unfortunately http://pve.proxmox.com/pve2-api-doc/ does not list any documentation regarding the new vncwebsocket command yet.

Maybe someone has already done this and can provide an example how to access from noVNC to Proxmox vncwebsocket API command?

@proxmox team: Does the proxmox API specify headers for CORS? The Java applet is working fine cross-site. Not so sure if Javascript might complain...

GUI cannot connect to ceph cluster

Hi,

I have set up a Proxmox VE 3.3 cluster with three nodes (HP ProLiant DL380 G6), with a ceph cluster on the same machines (all three nodes currently have two disks used as OSDs).
I am using 1 NIC for the public-facing side (vmbr0 with eth0) and three NICs with bonding for the storage and cluster communication (vmbr1 on bond0). The /etc/network/interfaces looks like this:
Code:
auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
    address PUBLIC_IPv4
    netmask 255.255.255.192
    gateway GATEWAY
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0

iface vmbr0 inet6 static
    address PUBLIC_IPv6
    netmask 64
    up route -A inet6 add v6PREFIX::/48 dev vmbr0
    up route -A inet6 add default gw v6PREFIX::1 dev vmbr0
    down route -A inet6 del default gw v6PREFIX::1 dev vmbr0
    down route -A inet6 del v6PREFIX::/48 dev vmbr0


auto bond0
iface bond0 inet manual
    slaves eth1 eth2 eth3
    bond_mode 4
    bond_miimon 100
    bond_lacp_rate 1
    bond_xmit_hash_policy 2
    bond_downdelay 200
    bond_updelay 200
    mtu 9000

auto vmbr1
iface vmbr1 inet static
    address 172.30.254.5
    netmask 255.255.255.0
    bridge_ports bond0
    bridge_stp off
    bridge_fd 0
    mtu 9000
    up route add -net 224.0.0.0 netmask 240.0.0.0 dev vmbr1
    down route del -net 224.0.0.0 netmask 240.0.0.0 dev vmbr1
In the storage network, the nodes have the addresses .5, .10 and .15.
In /etc/hosts, the storage network IPs are connected to the hostname and AFAICT, all cluster and storage traffic is going through the bond.
I was able to set up the OSDs and the pool via the GUI and I could also add the RBD storage that way. My /etc/pve/storage.cfg looks like this:
Code:
rbd: pool-ceph01
    monhost 172.30.254.5 172.30.254.10 172.30.254.15
    pool pool-ha01
    content images
    username admin
The Ceph storage is properly shown on each node in the GUI. However, if I select the storage and click the "Content" tab, I cannot do anything, but rather get the error message
Quote:
rbd error: rbd: couldn't connect to the cluster! (500)
I am rather new to PVE, so I was not entirely sure where to look for the reason (of course I searched the web, but this error seems to be not very common). However, I tried to look through the logs in /var/log, where I couldn't find anything suspicious.

Any hints on a possible reason or a place to look at are highly appreciated. If you need more information on the setup, I will provide them ASAP.

Thank you very much!

Proxmox Repository extremely slow - Homepage, Wiki & Forums too

Hy there,

I have a problem when I access any Proxmox server (Homepage, Wiki, Forums, Repository)
When I try updating Proxmox (with Enterprise Repository) it is so extremly slow that I get errors:

"Empty reply from server"
"Operation too slow. Less than 10 bytes/sec transferred the last 120 seconds"

And when I access the wiki or the forums it takes a very long time to load.
I have this problem for weeks now and have configured nearly everything on my operating system, router (FritzBox) and so on.
This happens only when I test Proxmox at home - in the datacenter it is fast as always.

Does anyone have this problem, too? Are there special configurations on the proxmox side so I get these errors (MTU?).
I don't have any extraordinary configs on my network, I tested it with IPv6 and with IPv4-only, too.

I'm very frustrated because I can't update Proxmox because it is SO slow. Sometimes it transferes some KiloByte, so there is a connection.


Thank you for any help!

Hello,
I have been looking for a way of displaying the core temperature of the cpu's on my proxmox machine over a length of time on the web interface.

I currently have been able to add a new graph on the node status page however i am unable to find out how to add a new data stream and how to populate it with information in order to show the cpu temperatures.

How would i go about creating a new data stream to be displayed in the graph tab i have made?

Also one other note how many data streams can i have displayed on one of the graphs at one time as i have only ever seen 2 on them.

VT-d and SR-IOV

I have been searching for a few days now trying to figure out what I'm missing. I have IOMMU enabled in BIOS and in proxmox and everything shows up as it should. I tried configuring SR-IOV and I get the same message several others have:
Code:
Not enoiugh MMIO resources for SR-IOV
The chip is the Intel 82576 which is on a Supermicro X8DTG-DF board. I confirmed that both the board and chip support SR-IOV and it is enabled in BIOS. After hours of trying to get it working I finally decided to install a separate card.
I installed the Intel 82571EB and tried passing it through to the VM using
Code:
qm set 102 01:00
(among other configurations) but consistently receive the error:
Code:
Failed to assign device "hostpci0.0": Operation not permitted
Being able to assign a dedicated nic is critical since this is to be used for pfsense.

KERNEL BUG: Bridge - Vlan id are not applied to multicast groups

October 3, 2014, 8:49 am
$

After a LOT of debugging i've found that the bridge vmbr0 of my host machine was propagating multicast traffic to the bridge without caring of vlan id.

To let me better explain, i've this setup:

VLAN 1 -> Native Vlan (no IPv6)
VLAN 2 -> Tagged vlan (with IPv6 autoconfiguration)

Interfaces:
eth1 -> Trunk interface (vlan 1 native and vlan 2 tagged)
vmbr0 -> VM bridge

I've discovered that after configuring IPv6 Router advertisement over a specific VLAN and I saw that other machines on the native vlan get automatically the addresses.
It seems that this beaviour it's mono-directional (from outside to inside the host machine) but it's sufficient to create troubles.

To check the issue you can simply run a couple of tcpdump:

Tcpdump run over the host machine
# tcpdump -e -s0 -A -i eth1 dst ip6-allnodes
tcpdump: WARNING: eth1: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

The bug seems to be already recognized and solved by this patch:
http://www.spinics.net/lists/linux-e.../msg04643.html

Workaround

a simple workaround could be done with ip6tables:

echo 1 > /proc/sys/net/bridge/bridge-nf-call-ip6tables
ip6tables -A FORWARD -i vmbr0 -p ipv6-icmp --icmpv6-type router-advertisement -j DROP

New Mini-itx Proxmox Build

Hello everybody,

Recently (disappointed by the hyper-v performance on my not so old pc) I decided that it's time to build a barebone home server and choosed Proxmox as my solution. After a vast research my ideas ended with low power, mini-itx home server containing the following:

  1. Mobo - GA-H97N-WIFI
  2. CPU - Intel-Xeon-Processor-E3-1231-v3-8M-Cache-3_40-GHz
  3. RAM - Some 2x8gb
  4. PSU - Something Like Seasonic ATX 460 or similar should do it.
  5. Case - HAF Stacker 915r - you never know how many of these you'll need
  6. 16-32gb USB 3.0 to boot from - Dumped in favour of one of a SSD - To be decided
  7. HDD/SSD - I have a spare drives laying around


By todays prices all is roughly 600$, a bit more than I am willing to spend, however, I can live with it. My goal is to run 5-6 vm - few windows servers, pfsense firewall, another linux server and few testing hosts, none of them with high load. Since I am new to the proxmoxing if someone is having a better setup/build in mind, please share
it, your opinions are more than welcome, I just don't wont to end with another crappy virtualization server, I already have one :)

I have two hosts -- an older one that's the master and a newer one which has all my VMs migrated to it. The older one has been off for a few days now, but of course, if we have a power failure or something, the VMs will not come back up on the newer one. How do I "de-cluster" this setup so the newer host is independent and has all the VMs?

Template from an OpenVZ container using the WebUI

Hi,
I want to convert an OpenVZ container into a template. I can see how to do this for KVM (there is a menu item) but there is no similar menu for OpenVZ.

http://www.jamescoyle.net/how-to/293...te-for-proxmox shows how to do this on the command line

http://www.jamescoyle.net/how-to/133...roxmox-web-gui provides a patch stating:

Quote:
The changes were declined by the Proxmox team on the grounds that creating a template is a technical process and may not result in creating a working, cloned instance. In addition, it is very easy to leave sensitive information in the CT which is the source of the template – all data on the CTs file system will be archived into the template making it available the next time a CT is created. If SSH keys are left on the CT, for example, then they will be available in the new CT also.

  1. Why is this okay for KVM and not for OpenVZ?
  2. Users of template containers are typically savvy administrators. A warning would suffice.
  3. There are some common scenarios, such as SSH keys. These can be detected and further warned about.


External patches proliferates use-case fragmentation, risks code drift and legitimizes the practice of more patching. That leads to unstability, hampers upgrades and can affect reputation of both stability and ease of use.

It seems to me that it's better to incorporate this feature and mark as caveats than leave it out in patch-land.

Regards, Martin.
