 |
|
Hello,
I can run my VMs using the superuser account, but I'm unable to run qemu under my user account. It fails on accessing KVM module.
| Code: | user@beacon ~/Virt $ ./WindowsVM.sh
Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied
No accelerator found!
|
my user account is in KVM group
| Code: | user@beacon ~/Virt $ groups
wheel uucp audio cdrom video games kvm usb portage user rfreader
|
and /dev/kvm permissions
| Code: | user@beacon ~/Virt $ ls -l /dev/kvm
crw-rw----+ 1 root kvm 10, 232 Apr 4 07:47 /dev/kvm
|
any guesses, what could be wrong?
Thanks |

What are you doing inside WindowsVM.sh?
Is the kvm module loaded before you run the shell script or are you trying to load it from the shell script?
Kernel modules need to be loaded by root.

Here is the content of WindowsVM.sh (copy-paste from some tut)
| Code: | #!/bin/sh
exec qemu-kvm \
-cpu host \
-drive file=WindowsVM.img,if=virtio \
-net nic -net user,hostname=windowsvm \
-m 1G \
-monitor stdio \
-name "Windows" \
$@

I do not have KVM as a module, it is hardwired in kernel (and it works with superuser privs) so there is no need to load KVM module tough. |

Don't know then, I run mine as modules.
I do have to run as root if I use passthrough (vfio), not sure if the same applies to virtio.
