    VMs freezing and unreachable when backup server is slow

    It's also worth mentioning that sometimes disabling "freeze-fs-on-backup" in the qemu agent settings (under VM > Options > QEMU Guest Agent > Freeze/thaw guest filesystems on backup for consistency ) can help preventing VMs freezing / crashing.

    Unified cgroup v2 layout Upgrade warning PVE 6.4 to 7.0

    You can bring the network interface up with dhclient or by setting a static ip, or you can copy the rpm's to your host and then transfer them over to the container. For example: $ pct enter YOURCONTAINERID $ dhclient $ wget...

    Proxmox Encryption

    Are there any plans of implementing this yet? Seems like the qemu/luks development is pretty active lately http://lists.gnu.org/archive/html/qemu-block/2017-01/msg00011.html

    [Unofficial] proxmox kernel 4.8.1

    Thanks for this! Any chance you'll update to 4.9 now that it's out?

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    @fabian Any ETA on that kernel? I'll be moving those servers in to production soon, so I'm running out of time to do further testing. @brad_mssw Yes that's what I'm assuming too and it's quite understandable, that's why it would be great if there is a solution/workaround to this issue we are...

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    Compiled the kernel with -d CONFIG_NET_RX_BUSY_POLL in the Makefile for the proxmox kernel, but it seems like it did not disable busy-poll

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    A test build would be good, I was underway of building it myself. Are there any plans of supporting 4.5+ in the forseeable future?

    Proxmox + IPMI + UEFI = Can't click next to install

    I've had this issue with IPMI and proxmox in the past, both on 3.X and 4.X. I can use tab/enter just fine, but if I click with the mouse somewhere in the IPMI KVM console prior to using tab/enter I can't use tab/enter. I wish proxmox would include a ncurses based installer alternative to the...

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    I've done some further testing, I still have not been able to pull any logs/stack traces in regards to this issue. I tried various combinations of turning off/on offloading settings with ethtool, but they did not seem to have any affect on this crash. ethtool -K eth2 gro off ethtool --offload...

    Ceph version in 4.3?

    10.2.5 is out! How soon can we expect Jewel in Proxmox? :) https://www.spinics.net/lists/ceph-devel/msg33953.html https://www.spinics.net/lists/ceph-devel/msg34018.html

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    Apologies, 4.4.30 is what I meant. 4.4.30 was running good for me for a few hours, survived reboots, etc. but then it suddenly began having problems. I'm switching over to 4.7 now to see if it really resolved the issue or if I just got lucky earlier. @markusd How did you manage to get that...

    Open vSwitch and incorrect RSTP (+ crash on topology change involving Mellanox 10GbE adapter)

    I've been experiencing similar issues to those described in this thread. I have 4 server nodes with Mellanox ConnectX-2 cards connected in a ring, with no external switch. I'm using the RSTP enabled config from the wiki. What I've been experiencing is the following: Sometimes when booting my...

    KVM vs Hyper-v 2012 Performances

    How does that "kill" Proxmox? You can have unlimited VM's with Proxmox without paying anything :)

    OFED for PVE

    You are talking about EoIB while I was talking about eIPoIB. But yeah, seems like eoib and eipoib aren't getting much attention lately unfortunately. I've been trying various setups on my Infiniband cards with the intention to get vm's running on ipoib. Installed OFED 3.4 Got ipoib and...

    OFED for PVE

    I understand the reaction from the upstream maintainers and agree with them, this is not the "proper way" of doing things. But it's a good workaround while no other solutions exist. I haven't found any information on EoIB or IPoIB moving in this direction yet. IPoIB is still layer 3 and that...

    OFED for PVE

    After taking a quick look at the sources from the Mellanox OFED 3.4 I can see that there are some differences from the V2 patch. I have not been able to find any newer merge requests on the kernel mailing list. But I did see that Oracle Linux accepted the eipoib driver back in 2013. The...

    OFED for PVE

    I have not seen any newer merge requests than that. The eipoib module is shipped with the most recent versions of the OFED package from both Mellanox (OFED 3.4) and from the OpenFabrics Alliance (OFED 4.8). I am however unsure if there have been any updates to the eIPoIB driver or if they are...

    OFED for PVE

    The Mellanox drivers that ship with the 4.4.21-1-pve kernel work great with my Mellanox ConnectX-2 cards. However the eIPoIB driver is missing. The eIPoIB driver enables bridging on the Infiniband IPoIB device, which allows us to use Infiniband for the guest machines. @fabian do you think...
