Idk why am I getting this error.

docker: Error response from daemon: error gathering device information while adding custom device "/dev/kvm": no such file or directory.
ERRO[0000] error waiting for container: context canceled

I know you opened this a month ago; but you likely don't have virtualization enabled in your bios.

I have it enabled idk what the issue was I switched to Arch, I wanted to try using Debian because stable, but switched because of this issue.

Installing extra/libvirt from Arch will give you this feature.

The error was on debian

The error was on debian

were you able to figure it out, i seem to be having the same problem. I have Kvm installed, i have virtualization enabled in bios. I've ran a Mac OS virtual machine normally but I'm now trying to do it through docker as the USB connection seems simpler.

Am afraid I wasn't able to, I had to deliver work so I just hopped back to Arch.

Same problem here.

What happen with Debian 12 bookworms and Ubuntu 24.04?

I create VM in GCP and there some issues:

1. Install necessary packages

   
   sudo apt install **qemu** qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager libguestfs-tools

then get the output

Note, selecting 'qemu-system-x86' instead of 'qemu-kvm' Package qemu is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'qemu' has no installation candidate

2. Find qemu repo and change it via https://www.qemu.org/download/#linux

sudo apt install qemu-system qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager libguestfs-tools

then nothing happen and there is no folder '/dev/kvm' were created.

3. Then, enable libvirt and load the KVM kernel module:

sudo systemctl enable --now libvirtd sudo systemctl enable --now virtlogd

echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs

sudo modprobe kvm

the output is

tee: /sys/module/kvm/parameters/ignore_msrs: No such file or directory 1

4. Reboot machine and there still no folder '/dev/kvm' so that when run docker there was error

Error response from daemon: error gathering device information while adding custom device "/dev/kvm": no such file or directory
