[libvirt] libvirt for rhel-5?
by Farkas Levente
hi,
is there any plan to be able to buils libvirt on rhel-5 ie. epel-5?
currently all virt and kvm releated packages can be build on epel except
libvirt since this dbus problem.
thanks in advance.

[libvirt] bug: libvirt hang while restore a domain
by Daniel Schwager
Hi,
i try to restore a domain without a valid disk (I deleted the diskfile
before restoring it ...). Normally, this must always produce an error.
** The first time, an error occurred - OK:
[root@xen03 srv]# virsh restore /srv/save
libvir: QEMU error : operation failed: failed to start VM
error: Failed to restore domain from /srv/save
** But the second time, the command hang:
[root@xen03 srv]# virsh restore /srv/save
^C
[root@xen03 srv]# virsh list
^C
[root@xen03 srv]#
I can't use libvirt now, until restarting the daemon....
*** The domain looks like this (/tmp/winxp100 does NOT exist)

[libvirt] kvm, sync guest disk before saving ?
by Daniel Schwager
Hi,
is there a way to get a consistent disk image of a domain running qemu-kvm
before saving it ?
I used " xm sysrq <id> s" with xen-hypervisor - but what's the way with kvm ?
Or could I install drivers into the guest helping to solve this problem ?
regards
Danny

[libvirt] invoking interface.script - missing interface name of domain
by Daniel Schwager
Hi,
i would like to write a small script
- bringing up my qemu-kvm interface and
- connecting it to a bridge
using the following XML domain-syntax :
....
<interface type='ethernet'>
<script path='/etc/kvm/qemu-ifup'/>
</interface>
....
The script will invoked (from qemu-kvm I thinkg) but
I can't find any arguments like "interface name" - so
my script cannot setup the bridge correctly because of
missing information about the interface name.
At the moment, I look to the PPID (parent pid of the script) and
parse the qemu commandline (ps ef) to find out the interfacename -
but it's only a workaround.
Q: Is there a way to get informed about the interface libvirt/quemu used
for the new domain ?
regards

[libvirt] [PATCH 6/8] Makefile.maint: sync from coreutils
by Jim Meyering
You can ignore the patch numbering.
There was yet another one adjusting po/POTFILES.in
that I'm not bothering to post.
Probably not worth reviewing.
Some of it is just factorization.
Other bits reflect removal of coreutils-specific things (they're
migrating into coreutils' cfg.mk (was called Makefile.cfg).
On the other hand, a few are introduction of cu-specific bits,
but that are enabled only if certain coreutils-specific files
are present. This is to make later merges easier.
I've made sure that "make syntax-check" still works.

[libvirt] PATCH: Fix crash in QEMU driver with illegal machine/arch info
by Daniel P. Berrange
This bug was originally reported here
https://bugzilla.redhat.com/show_bug.cgi?id=479203
If you define an guest VM specifying a architecture which does not
actually exist in the QEMU driver's declared capabilities, then it
would dereference NULL when later attempting to start the VM.
The example from the bug, is attempting to create & start a 'x86_64'
VM on a host which is i686, and doesn't have the qemu-system-x86_64
emulator available. Or even just make up a random bad architecture.
This patch does two things
- Makes the domain_conf.c parser validate the requested architecture
against those actually available in the driver
- Safety net in qemu_conf.c just in case the former validation somehow
stopped working.
With this patch applie you now get
# virsh define demo.xml
libvir: Domain Config error : internal error os type 'hvm' & arch 'x86_64' combination is not supported
error: Failed to define domain from demo.xml
Regards,
Daniel

[libvirt] PATCH: Support VNC password for QEMU guests
by Daniel P. Berrange
This patch adds support for using the monitor interface to set the VNC
password
(qemu) change vnc password
Password: ********
A minor tricky thing is that we can't just send the command and password
all in one go, we must wait for the 'Password' prompt before sending the
password.
When doing this I noticed that virsh dumpxml has no way to request a
secure XML dump (required to see the password element), nor did the
virsh edit command set the SECURE or INACTIVE flags when changing
the XML.
