[Libvir] suspended domains
by Vadim Zaliva
I am using libvir 0.4.1 with Xen 3.2.0. It might be an obvious
question, but if there is a way to get list
of inactive/suspended domains via C API?
virsh # list --all
Id Name State
----------------------------------
0 Domain-0 running
6 centos51 blocked
virsh # domstate centos52
paused
As you can see 'centos52' is not shown, although it is known.
In general, could somebody explain to me how libvirt is managing
information about inactive
domains?
Thanks!

[Libvir] PATCH: Add SCSI HBA backend for storage driver
by Daniel P. Berrange
This patch adds a new backend to the storage driver supporting SCSI HBAs.
With this you can now enumerate physical disks provided by FibreChannel,
internal SCSI / PATA / SATA / USB adapters.
The implemention uses HAL to enumerate the volumes asssociated with an HBA.
It is common for most boxes to support multiple HBAs. eg on my Linux laptop
$ ls /sys/class/scsi_host/
host0 host1 host2 host3
These HBA names are used to identify the host when defining the XML:
<pool type="scsi">
<name>hba0</name>
<source>
<adapter name="host0"/>
</source>
<target>
<path>/dev/disk/by-path</path>
</target>
</pool>
This does not provide any means of discovering HBA names - that's a later
piece of broader work on host device discovery. It also does not support
multipath devices (eg with FibreChannel the same storage volume can appear
on the host multiple times)
Example using the first host adapter which is my internal SATA controller
with a single disk attached:
# ./src/virsh pool-create /root/hba0.xml
Pool hba0 created from /root/hba0.xml
# ./src/virsh vol-list hba0
Name Path
-----------------------------------------
0:0:0:0 /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
# ./src/virsh vol-info /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
Name: 0:0:0:0
Type: block
Capacity: 153.39 GB
Allocation: 153.39 GB
# ./src/virsh vol-dumpxml /dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
libvir: Storage error : no storage vol with matching key
<volume>
<name>0:0:0:0</name>
<key>SATA_HDT722516DLA380_VDK91GTE0WPLER</key>
<source>
</source>
<capacity>164696555520</capacity>
<allocation>164696555520</allocation>
<target>
<path>/dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0</path>
<permissions>
<mode>060640</mode>
<owner>0</owner>
<group>6</group>
<label>system_u:object_r:fixed_disk_device_t</label>
</permissions>
</target>
</volume>
This also does not deal with the problem of HBAs being created on the fly,
eg the NPIV case where you can add/remove adapters at will. I'm still working
on how to deal with this. If you have your virtual NPIV adapters already
defined though, it can enumerate them fine.
Aside from the bit where I map from the short HBA name (eg 'host0') into the
HAL device name, this should be portable to Solaris as-is.
Dan.

[Libvir] [PATCH] reindent __virErrorMsg with spaces instead of tabs

[Libvir] [PATCH] Another Report error in virsh.c code.
by S.Sakamoto
Hi,
I am watching through the virsh code for same type bug check.
http://git.et.redhat.com/?p=libvirt.git;a=commit;h=c857ace66df5a5068ed561...
And I found another point it should report error.
Thanks,

[Libvir] [PATCH] Add Xen Scheduler APIs to xenDaemonDriver
by Saori Fukuta
Hi,
I add the Xen Scheduler APIs to xenDaemonDriver.
- xenDaemonGetSchedulerType
- xenDaemonGetSchedulerParameters
- xenDaemonSetSchedulerParameters
We will have the following improvements by this patch:
1) xenDaemonDriver of Schedulr is usable
when xenHypervisorDriver failed.
2) Show the Scheduler information with non-root user.
3) Set the Scheduler parameters for inactive domain.
(Unfortunately not right now, because we need this fix.
http://lists.xensource.com/archives/html/xen-devel/2008-03/msg00301.html)
And I have a few things to note:
- Currently, implemented for the Xen-credit scheduler only.
- xenDaemonGetSchedulerType is supported in xendConfigVersion >= 4,
because we can get "xen_scheduler" from xend after Cset13394 of
Xen (i.e. xendConfigVersion is four or later).
- For the above reason, xenDaemonGetSchedulerParameters and
xenDaemonSetSchedulerParameters are also supported in
xendConfigVersion >= 4, because they are using xenDaemonGetSchedulerType
to get the scheduler type.
- At xenDaemonSetSchedulerParameters, there are restrictions
which depends on Xend-version.
a) We cannot set the "cap" value by xend before Cset15476 of Xen,
because xend does not support the "cap" value
at xend/server/SrvDomain.py
b) We cannot set the scheduler parameters for inactive domain
without the following patch.
http://lists.xensource.com/archives/html/xen-devel/2008-03/msg00301.html
If the above patch is committed, this API will be available
for inactive domain.
Regards,
Saori Fukuta

[Libvir] Adding suppport for daemon restarts with stateful drivers
by Daniel P. Berrange
The libvirt daemon has the ability to reload itself by sending it SIGHUP.
For the QEMU & network drivers this makes it reload the config files for
VMs and re-init the iptables rules. It would be desirable though to allow
the daemon to perform a full restart. Principally this is for RPM upgrades
where you want toensure the daemon is running the new code.
The tricky thing is figuring out how to handle driver state. Looking at the
QEMU, network, storage and LXC drivers, there is not actually all that much
state to deal with. It basically comes down to:
- PID of child processes (eg QEMU, dnsmasq, container)
- FDs for STDIN/OUT/ERR of the child processes
- A possible logfile FD
- Flag to indicate whether some objects are active or not
That is more or less it. Anything else is kept in the config files and can
be reloaded at will.
So I was thinking about whether we could provide a simple protocol to allow
each stateful driver to save its state into some location, the daemon could
just 'exec()' itself again, and upon startup the drivers reload their active
state. Since the daemon just exec()'s itself it would still own the child
processes & still have all the neccessary FD's open.
Dan.

[Libvir] [RFC] 0 of 4 Linux Container support
by Dave Leskovec
Greetings,
Following are the patches adding linux container support. The first three
patches are updated versions of the original three I posted. They've been
updated for the feedback I've received so far and to include some other recent
libvirt changes. The last patch adds support for starting a container. Still
working on shutdown and destroy but wanted to get the start code out for comments.
The XML format has been updated to this:
<domain type='linuxcontainer'>
<name>TestContainer1</name>
<os>
<init>/home/dlesko/src/dev/lxc/lxc_rcinit</init>
</os>
<memory>65536</memory>
<devices>
<filesystem type='mount'>
<source dir='/home/dlesko/lxc_files/tmp/'/>
<target dir='/tmp/'/>
</filesystem>
<console tty='/dev/ptmx'/>
</devices>
</domain>
All comments and questions are welcome.
