Hi,
I looked around a bit and wasn't able to find a good answer to this, so

Since Xen 4.12, credit2 is the default scheduler, but at least as of
libvirt 5.1.0 virsh doesn't appear to understand credit2 and produces
this sort of output:
# xl sched-credit2 -d yw6hk7mo6zy3k8
Name ID Weight Cap
yw6hk7mo6zy3k8 4 10 0
# virsh schedinfo yw6hk7mo6zy3k8
Scheduler : credit2
Compared to a host running credit:
# xl sched-credit -d gvz2b16sq38dv9
Name ID Weight Cap
gvz2b16sq38dv9 14 800 0
# virsh schedinfo gvz2b16sq38dv9
Scheduler : credit
weight : 800
cap : 0
Trying to change the weight does nothing, not even producing an error
message:
# virsh schedinfo syuxplsmdihcwc --weight 300
Scheduler : credit2
# xl sched-credit2 -d syuxplsmdihcwc
Name ID Weight Cap
syuxplsmdihcwc 23 400 0
Is there a version of libvirt where I can expect this to work, or is it
not supported yet? As a workaround for now I've added sched=credit to
my command line, but it would be nice to gain the benefits of improved
scheduling at some point.
