qemu

I've been running Proxmox on a new AMD Ryzen 1700x server for the last few weeks and because I'm using GPU passthrough I've been using the testing repository because of certain AMD patches that are available in the newer kernel, this has been working great! Yesterday I decided to run an apt...

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...

Hi, For quite some time, I have been experimenting with using the QEMU Agent from the commandline. I have enabled the agent from the web gui and installed the qemu-agent package in my guest. I am getting the results but I am not able to the same in a scripted manner. Here is what I am doing...

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...
