It seems downgrading to 6.3-3 using below commands will fix the issue:
apt install pve-manager=6.3-3
The sign of issue is that some VMs show CPU usage of exactly 0% and VNC will not be able to connect and also you can see lines like below inf /var/log/syslog
VM 1116 qmp command failed...
In last few days my latest Proxmox installation on AMD CPUs has VM freezing issue.
My CPUs in different servers was in two models:
1.AMD Ryzen 9 3900 12-Core Processor
2. AMD EPYC 7401P 24-Core Processor
On both I can see Windows VMs freez after free hours, and stop/starting them will temporary...
As far as I have tested with more than few servers, whenever I install Proxmox on a Hetzner server for example AX or PX lines, my servers go down and when I check them out with remote KVM the screen is blank.
The only temporary solution is to reboot the server and they just come up fine.
For purpose of fast provisioning we need to be able to clone a base LVM, which is raw OS image on it,
Is that possible like what below link said in shared storage environment? ( of course we have SAN storage device)
In latest versions of kernel 5.2+ we can disable mitigations by "mitigation=off" kernel command, but as Proxmox 6 is using kernel 5.0 I've disabled them by using this grub config
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 pti=off spectre_v2=off nospec_store_bypass_disable mds=off"
For better Ceph performance, I need to disable all kind of kernel protections for CPU vulnerabilities,
Is there any guide on how to ask kernel in Proxmox to do so?
Servers are being used only for Ceph so I have no security concerns regarding disabling CPU vulnerabilities.
I setup OVS switch on 10 nodes which are interconnected via GRE tunnels, but I can see Proxmox is not letting us create more than 4094 vlans because tag ID larger than 4094 is not validated in Proxmox interface or API.
Is there any restriction based on GRE overlay that prevent us having more vlans?
