[libvirt] PATCH: Avoid crashing valgrind in LXC driver
by Daniel P. Berrange
The LXC driver makes use of new clone flags for creating containers. It
creates a dummy container which immediately exits in order to test for
availabilty of this feature in the kernel. Unfortunately valgrind has
no knowledge of these new clone flags, gets very very unhappy and then
reports bogus memory leaks, bogus illegal instructions, and then often
SEGV's itself. Not cool. While obviously valgrind needs fixing, I looked
at its code, and it doesn't seem easy, so this patch adds a quick check
for a LD_PRELOAD environemnt variable which contains a library whose
name contains 'vgpreload'. If it sees this, LXC driver totally disables
itself. This lets me reliably valgrind the libvirtd daemon again.
Second, I also move the lxcProbe() call in the lxcOpen() method down a
little, so we only probe if we are actually about to try opening the
connection. This avoids some unneccessary container creation checks
for most virConnectOpen scenarios.

[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....

[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

[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
