qemu

This morning, I updated my home server from PVE 5.1-43 to 5.1-46. Before the update, I had a handful of QEMU VMs that I configured serial sockets for so that I can use xterm.js (it's much faster when I'm on the go since I have a very restrictive bandwidth that noVNC can't quite make it through)...

Hello I've seen some vulnerabilities in qemu-kvm, that were recently patched. For ex, CVE-2017-7980 In the redhat announcements, i saw they require a stop of all VMs for the update to take effect. Do we need to follow the same procedure when proxmox updates the qemu? Or it's patched in...

Hello there, I saw in the device manager this unknown device "ACPI\QEMU0002" and already googled about it and tried all virtio drivers. But none is correct. I also installed qemu guest-agent, but it didn't solve the issue. I've got this problem on Windows Server 2012R2 Essentials and Standard...

Hi guys, Need some bright minds in the Proxmox community :) I setup a storage cluster using Ceph (as the title suggests). It's a fairly large cluster consisting of over 200 osds. When I bench the cluster using rados bench, I get exactly the kind of performance I was expecting to get... doing...

I thought qemu-2.7 had solved all issues regarding iothread but apparently you are still not able to make a backup if iothread is enabled. Am I missing something?

Dear Users, I would like to ask everything if there is any possibility with Proxmox/KVM known to change the values of the motherboard information in smbios. I know that is already possible to modify the system information, but I'am also looking for an option to change the motherboard values...
