 |

Hey!
Gentoo runs on my test server, so i don't use it day by day. Since a while starting virtual machines on the system fails:
| Code: | virsh start vm1
error: Failed to start domain vm1
error: Unable to create vcpu cgroup for vm1(vcpu: 0): No such file or directory |
I read, that cgroups came into the kernel some time ago and libvirt uses it since some weeks. I don't know how to troubleshoot.
This is, what i can say:
Kernel: 3.10.0-hardened
app-emulation/libvirt-1.0.5.2
| Code: | cat /usr/src/linux/.config | grep CGROUP
CONFIG_CGROUPS=y
# CONFIG_CGROUP_DEBUG is not set
CONFIG_CGROUP_FREEZER=y
CONFIG_CGROUP_DEVICE=y
CONFIG_CGROUP_CPUACCT=y
CONFIG_CGROUP_PERF=y
CONFIG_CGROUP_SCHED=y
CONFIG_BLK_CGROUP=y
# CONFIG_DEBUG_BLK_CGROUP is not set
CONFIG_NET_CLS_CGROUP=y
CONFIG_NETPRIO_CGROUP=m
cat /etc/rc.conf | grep cgroup
# If you have cgroups turned on in your kernel, this switch controls
# /sys/fs/cgroup.
# Support for process management by cgroups is planned in the future,
rc_controller_cgroups="YES"
cat /proc/cgroups
#subsys_name hierarchy num_cgroups enabled
cpuset 2 2 1
cpuacct 3 2 1 |
virsh wants me to create a vcpu group within cgroup?! How can i do that?
Thanks for any help |
