Re: [libvirt] virsh sechedinfo/memtune with libvirt-0.8.8

Hi The bugzilla advice/patch below is not relevant here . Please see what is the reason for virsh schedinfo / memtune not woking with libvirt-0.8.8 and libcgroup-0.36 while it does work with libvirt-0.8.3 and same libcgroup . Please dispatch to the appropriate person if you know the guy in charge.

AFAIK, it's some problem of libcgroup: https://bugzilla.redhat.com/show_bug.cgi?id=640282 Guess following will work for you: # cgclear # cgconfigparser -l /etc/cgconfig.conf Regards Osier -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
