[my apologies for this re-post. I stupidly managed to hide the first
instance of this mail away in an unrelated patch-thread and am thus
afraid that the people who could have answered didn't see it]
Hi,
I have one test host running Debian unstable (kernel 2.6.32.3), and I
would like to virtualize on it using KVM and virsh. Debian unstable
has libvirt 0.7.5.
On this host, I cannot start any KVM domain using console with these
XML parts:
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target port='0'/>
</console>
When I try virsh start $domain, I get the error message:
error: internal error no assigned pty for device serial0
When I remove the serial and console stanza, the machine starts up.
This is the configuration documented everywhere. At first, I suspected
a change in the configuration syntax and filed Debian bug #565145, But
on the #virt IRC channel, people suggested that there was a change in
libvirt parsing KVM's output, which may be a genuine bug breaking the
console.
Is this already a known issue? Can I do anything to help debugging?
Greetings
Marc

Hi, Marc,
Could you please post the full domain XML, and the QEMU command line it
generated? You can get the latter from
/var/log/libvirt/qemu/<domain>.log. Can you also post the versions of
qemu and libvirt?
This should let me see where it's going wrong.
Thanks,
Matt

Took that patch, applied it to Debian's 0.7.5-4 source package, built
the package, installed it, same error.

Looks to me like the issue is still present in git head.
git clone
./autogen
create debian/ to allow building the debian package
rm debian/patches/series
rm docs/Makefile.am
touch docs/Makefile.am
autoreconf
debuild
dpkg --install
issue still present.

Get QEMU pty paths from the monitor
This is not a big surprise ;)
I'm going back to 0.7.4 for the mean time, but am prepared to test
things over the weekend. I will only have intermittent access to a
KVM-able host starting monday though, so it would be good if we sorted
this out over the weekend.

ii kvm 72+dfsg-2 Full virtualization on x86 hardware
This turned out to be the problem, libvirt didn't handle KVM 72's
output correctly. photron helped identifying this issue on IRC, which
I really appreciate, and there is a patch available to fix libvirt
0.7.5 with old KVM again.
The real issue was that Debian has renamed the kvm package to
qemu-kvm, which I didn't notice, and continued using an ancient kvm
version. qemu-kvm from Debian unstable works fine with libvirt 0.7.5.

Can you point me to this patch? Libvirt should be able to
run with kvm
72 too.
