Re: [libvirt] qemu logging/tracing option in domain xml

Hi all,
QEMU has the '-d' command line option to configure logs/traces.
As I can see, <qemu:commandline> is the only way to set it in domain xml.
<qemu:commandline> makes a configuration tainted and doesn't allow to update
tracing/logging configuration in runtime. The ability to update
configuration in runtime will be very useful for us in Virtuozzo for QEMU
problem investigation and development.
So I want to ask you will you mind if I prepare a patch-set that introduces
a new section for domain xml with next scheme:
<element name="debug">
<zeroOrMore>
<element name="log">
<attribute name="name">
<ref name="filter-param-value"/>
</attribute>
</element>
</zeroOrMore>
</element>
Is this acceptable?
IMHO I've always considered <qemu:commandline> to be appropriate for these
ad-hoc developer debugging flags. In addition I'm not hugely interested in
adding APIs for controlling QEMU's debugging facilities, since I think
these QEMU monitor commands are inherantly hypervisor specific.
