Source: libvirt
Version: 5.0.0-4
Severity: serious
For a few days/weeks (I'm not sure when it started exactly), I can no
longer run my VM with virt-manager.
On startup of libvirtd I have many messages like this one (one for each VM
I guess):
libvirtd[8281]: invalid argument: could not find capabilities for arch=x86_64
domaintype=kvm
When I try to start a VM I see this in the logs of libvirtd:
libvirtd[12569]: Unable to read from monitor: Connexion ré-initialisée par le
correspondant
libvirtd[12569]: internal error: qemu unexpectedly closed the monitor: Could
not access KVM kernel module: Permission denied
2019-06-22T17:07:23.635870Z qemu-system-x86_64: failed to
initialize KVM: Permission denied
libvirtd[12569]: internal error: process exited while connecting to monitor:
Could not access KVM kernel module: Permission denied
2019-06-22T17:07:23.635870Z qemu-system-x86_64: failed to
initialize KVM: Permission denied
But I do have /dev/kvm and I have hardware virtualization enabled in the
BIOS.
$ ls -al /dev/kvm
crw-rw----+ 1 root root 10, 232 juin 22 19:07 /dev/kvm
$ getfacl /dev/kvm
# file: dev/kvm
# owner: root
# group: root
user::rw-
user:rhertzog:rw-
group::---
mask::rw-
other::---
And I do have the required kernel modules:
$ lsmod|grep kvm
kvm_intel 245760 0
kvm 724992 1 kvm_intel
irqbypass 16384 1 kvm
I also have qemu-kvm installed:
$ dpkg -l qemu*|grep ^ii
ii qemu-kvm 1:3.1+dfsg-8 amd64 QEMU Full virtualization on
x86 hardware
ii qemu-system-common 1:3.1+dfsg-8 amd64 QEMU full system emulation

ii qemu-system-x86 1:3.1+dfsg-8 amd64 QEMU full system emulation

ii qemu-user 1:3.1+dfsg-8 amd64 QEMU user mode emulation
binaries
ii qemu-user-static 1:3.1+dfsg-8 amd64 QEMU user mode emulation
binaries (static version)
ii qemu-utils 1:3.1+dfsg-8 amd64 QEMU utilities
I removed virtualbox and rebooted to make sure it's not a bad interaction but
it did not help.
I don't know what else I should look into.
