We would like to use virDomainQemuMonitorCommand to query qemu independently of
libvirt state. Currenly it is not possible. This API call takes job condition
just like any other call and thus is unavailable on any lengthy(or stucked)
I've already posted this question in list, just failed to find the reference.
Somebody suggested to use proxy (and even an implementation) in between qemu
and libvirt that can inject commands to qemu and filter replies. It is not
really convinient. This way test setups will be different from production and
we can not investigate problems in production environment.
I'd like to drop acquiring job condition in the call as this function does not
deal with libvirt state (except for the taint but is is ok, we will not mess
things up here). But this is not enough, we need to make qemu monitor deal with
many qemu commands simultaneously. Looks like it is quite a big change for
test/debug case. But I guess eventually normal user cases can get benefits too
from this monitor changes. For example all query API calls that query qemu
directly can be changed to not to wait for some synchronous job
finishing.(qemuDomainGetBlockJobInfo for example).
