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...
