[libvirt] nodedev-list and qemu
by arnaud.champion＠devatom.fr
?Hi,
I've just installed libvirt 0.8.7 on my fedora x86_64 14 test host. It seems that the function virNodeNumOfDevices is no more supported by the qemu driver. Is that true ? or I'm wrong anywhere ?

[libvirt] Connecting with a remote libvirt
by Marcela Castro León
Hello
i'm trying to connect with a remote libvirt.
The option I selected was tcp because it's a development environment and a
secure and isolated network,
I've configured
listen_tcp = 1
tcp_port = "16509"
in libvirtd.conf at the destition.
I've tried to connect to host "santacruz" from a remote host "aoniken" and
locally but pn both cases I've got:
REMOTE
marcela@aoniken:~$ virsh -c qemu+tcp://santacruz:16509 list
error: unable to connect to libvirtd at 'santacruz': Connection refused
error: failed to connect to the hypervisor
LOCALLY
radic@santacruz:/etc/libvirt$ virsh -c qemu+tcp://santacruz:16509 list
error: unable to connect to libvirtd at 'santacruz': Connection refused
error: failed to connect to the hypervisor
I've try to use ssh but i've got an error two on both cases.
REMOTE (SSH)
marcela@aoniken:~$ virsh -c qemu+ssh://radic@santacruz list
radic@santacruz's password:
error: internal error no QEMU URI path given, try qemu:///system
error: failed to connect to the hypervisor
marcela@aoniken:~$
radic@santacruz:/etc/libvirt$ virsh -c qemu+ssh://radic@santacruz list
radic@santacruz's password:
error: internal error no QEMU URI path given, try qemu:///system
error: failed to connect to the hypervisor
Can you help me?
Thank you

[libvirt] Logging VM startup and shutdown
by Ed Swierk
When troubleshooting a libvirt system the most obvious question I face
is when a given VM started and stopped.
The only way I've been able to obtain this information is by setting
log_level = 1 in libvirtd.conf, which turns on the firehose,
generating an enormous amount of output. I then have to sift through
the logs for magic strings like "virExecWithHook" to see when a VM
started, and "Shutting down VM" to see when a VM stopped. Is there no
concise message that indicates a VM starting up? "virExecWithHook"
doesn't exactly jump out.
I'd consider starting up and shutting down a VM to be at least worth
an info-level message in the log. I monkeyed with the log_filters
setting but I couldn't figure out how to filter those two strings. Any
hints?

[libvirt] libvirt 0.8.7 LOCALSTATEDIR ubuntu patch
by Philipp Schmid
Hi,
I'm using ubuntu for our libvirt/kvm host server and needed IPv6 connectivity, so I started to update the latest ubuntu libvirt package (0.8.5) to 0.8.7.
I got all but one ubuntu specific patch to apply. The patch moves the ebiptables script from /tmp to "LOCALSTATEDIR" /lib/libvirt.
I renamed LOCAL_STATE_DIR in the patch below to LOCALSTATEDIR, because this seems to have changed between 0.8.5 and 0.8.7, but I still get the following compile error.
Since this is my first contact with the libvirt source or build system, I would be happy for any pointers on how to fix this and make LOCALSTATEDIR visible to nwfilter/nwfilter_ebiptables_driver.c.
Best regards,
Philipp Schmid
PS: if anyone is interested in working (at least for me with kvm) packages (without the mentioned patch), you can grab them here: http://www.schmidp.com/public/libvirt_0.8.7_ubuntu_natty/

[libvirt] [PATCH] storage: Allow to delete device mapper disk partition
by Osier Yang
From: root <root(a)amd-1352-8-2.englab.nay.redhat.com>
The name convention of device mapper disk is different, and 'parted'
can't be used to delete a device mapper disk partition. e.g.
[root@amd-1352-8-2 ~]# virsh vol-list --pool osier
Name Path
-----------------------------------------
3600a0b80005ad1d7000093604cae912fp1 /dev/mapper/3600a0b80005ad1d7000093604cae912fp1
[root@amd-1352-8-2 ~]# parted /dev/mapper/3600a0b80005adb0b0000ab2d4cae9254 rm p1
Error: Expecting a partition number.
This patch introduces 'dmsetup' to fix it.
Changes:
- New function 'virIsDeviceMapperDevice' in src/utils/utils.c
- Delete 'is_dm_device' in src/storage/parthelper.c, use
'virIsDeviceMapperDevice' instead.
- Requires device-mapper for 'with-storage-disk' in libvirt.spec.in
- Check 'dmsetup' in configure.ac for 'with-storage-disk'
- Changes on src/Makefile.am to link against libdevmapper
- New entry for 'virIsDeviceMapperDevice' in src/libvirt_private.syms
e.g.
[root@amd-1352- ~]# virsh vol-list --pool osier
Name Path
-----------------------------------------
3600a0b80005ad1d7000093604cae912fp1 /dev/mapper/3600a0b80005ad1d7000093604cae912fp1
[root@amd-1352- ~]# virsh vol-delete /dev/mapper/3600a0b80005ad1d7000093604cae912fp1
Vol /dev/mapper/3600a0b80005ad1d7000093604cae912fp1 deleted
[root@amd-1352- ~]# virsh vol-list --pool osier

?Hi,
in domain xml description, for the NIC interfaces, there is a model that specify the model of NIC exposed to the domain. I've understand that the model is driver dependent. Is there a way to know what is the driver default model ?
