Guys, how can I change the default resolution of 1028x768 to something else on guest VM with Windows 10? I changed the default resolution in the bios OVMF (UEFI) to 1920x1080, but when i start guest OS it still has default resolution of 1028x768. I use it without Display (none), but with GPU...

Nope, I never touched sounds configs. I just needed stable VMs and host server.

It disables power saving.

Yep, I tried to upgrade and downgrade cpu firmware. Nothing helped me.

I noticed that mce errors occured randomly, I couldn't correlate them with anything. Yep, I saw the same errors except that my CPU was i9-9900K. That's a CPU bug, as described here https://bugzilla.kernel.org/show_bug.cgi?id=109051

Yep, I've fixed that by adding intel_idle.max_cstate=1 to the file /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0 intel_idle.max_cstate=1" then upgrading grub and rebooting # update-grub That was an Intel CPU bug described here...

For whole host of course. I don't know but it's solved all my issues.

I wanted to say I've solved this bug timeout waiting on systemd and permanent crashing by adding intel_idle.max_cstate=1 All Servers and VMs are stable now.

Guys, do you use Intel CPUs who have the timeout issue? Because I had some issues with my Hetzner Servers on Intel CPUs including this and seems was able to fix them by adding intel_idle.max_cstate=1 to the file /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0...

I have the same issue on one of my server. Downgrading to proxmox-ve: 6.0-2 didn't help.

I got a new server, but I still lose access to it randomly and can see these errors: Jul 30 03:01:16 E3S kernel: [21083.991177] mce: CPU8: Package temperature above threshold, cpu clock throttled (total events = 1) Jul 30 03:01:16 E3S kernel: [21083.991178] mce: CPU9: Package temperature above...

It looks like Intel CPU firmware bugs. After downgrading cpu firmware I can't see mce: [Hardware Error]: Machine check events logged after rebooting. Still testing it.

I got a new server and found some issues during loading and adding new VMs. At first it froze, but after Proxmox upgrading it restarts automatically. It prints 'Start all VMs and Containers' in the tasks. Provider tested its hardware and didn't found any problems. But I can see mce: [Hardware...

Anybody knows about working Proxmox passthrough for guest Windows XP on intel integrated GPUs? I'm going to order several servers but couldn't find any info about GPU passthrough for Windows XP

Almost all my Guest VMs (Windows XP) lose network connections occasionally. The only one way to recover it is to stop and start VM again. If I look at the VM via Web ProxmoxVE it displays: Network Divece displays: e1000=X.X.X.X.X.X,bridge=vmbr0,link_down=1 If I click on the network device and...

Finally, I got it working. I had conflicts with librbd1 and librados2. These commands helped me: apt-cache policy librbd1 apt-cache policy librados2 I have another question: I installed proxmox-ve 4.2-64 on my Server#1. But the rest use proxmox-ve 4.2-66, I guess from pve-no-subscription...

Of course I followed these instructions, but was able to upgrade Kernel only up to 4.4.8-1-pve. Proxmox-ve is not installed and returns the same errors: # apt-get install proxmox-ve Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not...

I've been trying to upgrade Proxmox from 3.x to 4 since yesterday. I managed to upgrade it for 3 of 4 servers, but couldn't upgrade for the latest one. After apt-get install proxmox-ve I got: apt-get install proxmox-ve Reading package lists... Done Building dependency tree Reading state...

Thanks, the problem was solved by re-installing guest's firewall which blocked connection.
