This happens once in ten years... I've had now some very hot moments at a large scientific organization where I run a entire rack of Proxmox servers and a Ceph cluster. Even the basic infrastructure was randomly down (Firewalls, DNS, DHCP ...). But it's OK. Sh1t happens. That's life! The...

Please help identify the common factors that cause this problem. I can confirm, that I had exact the same issue as described by @Tim-AU and @Lephisto Still looking for the code different or added in kernel 6.8 causing this issue. * I'm using in the VM CPU host, is this the same in your case? *...

Asrock and Asus are server vendors And we have a good relation with them. And this Is not the case of RX570. As I wrote in my previous post, I'm aware of three different situations of 6.8 freezing - non of them applies to a epyc (non GPU) server. The RX570 relates to the Destroy DC context...

solved! it is definitely a kernel 6.8 bug i need to know which kernel patch/commit is causing this regression i'm looking in to ubuntu kernel and are the any proxmox specific patches? i will share this kernel problem with asrock and asus vendor

we need to know, what changed in kernel 6.8 and when it would be save, to go upstream again are the any proxmox specific kernel patches? tried kernel 6.8 without success: amd_iommu=off iommu=off default - no parameters and with ceph optimatizations amd_iommu=on iommu=pt pcie_aspm=off with...

after many attempts replacing PSU, CPU, RAM etc... trying different kernel parameters etc... checking ipmi and system for any error and logs checking all power cables and upgrading UPS updating BIOS, Firmware and BCM/IPMI BIOS configuring different options installing a new version of...

This thread is dedicated to the issue where the server just freezes. If the kernel gives error messages when the server crashes there is a thread https://forum.proxmox.com/threads/random-6-8-4-2-pve-kernel-crashes.145760 and not AMD GPU related as in...

Solved there is no bonding involved just the kernel (version) + bnxt_re module + Broadcom firmware + initializing RDMA RoCE I had the same problem. In my rack there are in total 25 pieces of Broadcom BCM57504 4x25G SFP28 PCIe network cards. Most of them do not have this problem, but some of...

solved! thanks fiona pinning machine type to 8.0 definitely helps i should have thought of this solution right away PS: this should be the right solution for all the virtual appliances from Cisco...

Upgrading Proxmox to 8.1.3 and pve-qemu-kvm to 8.1.2-4 from Proxmox 8.0.4 and pve-qemu-kvm 8.0.2-6 did cause AsyncOS to stop working properly. The VM is booting and starts, but this upgrade causes the newest AsyncOS to be non functional. The network is not working (network virtio) and at the...

the bug is related to some powersave functions (EEE or green ethernet etc.) on the switch with the combination of linux kernel found some kernel bug reports -> solved

OK - the 6.2 kernel is a nice one - but it doesn't help I'm running 20 proxmox ve or pbs and only some of them are affected by this bug. Next i will fiddle around with the switch (all affected systems are on one switch) the switch is fine and ok (i can achieve 1gbs on the same ports but with...

I have the same issue on proxmox ve and proxmox backup server Intel nics do wrong auto negotiation, realtek and broadcom are ok the cables are ok (they work in other scenarios) the switch is cheap but ok (other servers do not have a problem to reach 1gbs) the nics are ok (they do 1gbs under...

the same issue on my servers...

this problem is replicable (tried 2 socket xeon E5645, 2 socket E5-2637 v2, 2 socket CPU E5-2620 v3, 2 socket CPU E5-2650 v4, 2 socket Xeon Silver 4216): install proxmox (tried 6.4 and 7.2 +7.3) create a vm with debian 8 or ubuntu 12.04 or lower on ceph or zfs (because virtio scsi is not...

Thank you, the most likely change is, that we started backing up virtuals using the Proxmox Backup Server. This could cause some stress on the IO. And it is probably the scsi subsystem... I found some old kernel bug "CPU freezes in KVM guests during high IO load on host" and this could be...

Hi everyone, I have an issue with VMs randomly freezing. IT happens multiple times a day at seemingly random times. Not all my VMs with old Linux kernel freeze at once but they are all affected at one time or another. I did not have issues with more recent Linux distributions. I think that...
