[libvirt] (how much) support for kqemu domain
by John Lumby
I am wondering about the extent to which "old" qemu-0.11.1 and kqemu-1.4.0 are supported by virt-manager.
I see I can specify --virt-type=kqemu on virt-install and it remembers domain type='kqemu', and does things such as refusing to start the vm if the kqemu kernel mod not loaded, but it seems it does not tack on the
-enable-kqemu -kernel-kqemu
options on to the qemu command line. There is really not much point in trying to start a qemu-based vm with neither hardware kvm nor kqemu ...
I can work around it with an override script to intercept the qemu command, but does anyone think virt-manager ought to do this for me?

[libvirt] [PATCH] virsh: Add daemon version reporting
by Michal Prívozník
From: Michal Privoznik <mprivozn(a)redhat.com>
'virsh version' might report against which version of libvirtd is
running.

[libvirt] [PATCH] docs: Make hvsupport.pl pick up the host device drivers
by Matthias Bolte
Annotate the ESX device driver dummy.
Refactor the udev and hal device driver strcuts to match the
common annotation pattern.

You do that by not asking for a read-only connection !
/**

*
* @param uri
* The connection URI
* @param readOnly
* Whether the connection is read-only
* @throws LibvirtException

*/
public Connect(String uri, boolean readOnly) throws LibvirtException
since your code does
conn = new Connect("qemu:///system", true);
you asked for it. Please read the docs/code !

[libvirt] Operation forbidden for read only access
by PREETHI RAMESH
I'm using libvirt's Java API bindingsa and i've opened a connection :
Connect conn=null;
Connect conn1=null;
Connect conn2=null;
Domain testDomain1 = null;
//connect to host vm
try{
conn = new Connect("qemu:///system", true);
System.out.println("exception ONE:");
} catch (LibvirtException e){
System.out.println("exception ONE caught:"+e);
System.out.println(e.getError());
}
//get the domain in host vm
try {
testDomain1 = conn.domainLookupByName("hda1");
System.out.println("exception TWO:");
} catch (LibvirtException ex) {
System.out.println("exception TWO CAUGHT");
//Logger.getLogger(Migrate.class.getName()).log(Level.SEVERE,
null, ex);
}
//check if domain is running
try{
System.out.println("Domain:" + testDomain1.getName() + " id " +
testDomain1.getID() + " running " +
testDomain1.getOSType());
System.out.println("exception THREE:");
} catch (LibvirtException e1){
System.out.println("exception THREE caught: "+e1);
System.out.println(e1.getError());
}
/*try{

Domain migrate1;

As planned the new release is available at:
ftp://libvirt.org/libvirt/
It is a rather large release with near 400 commits included. From
an user point of view the main improvement is likely to be when
using migration as various work has been done to extend the protocol
and to avoid having the migration command stop other concurrent
operations (like virsh list). See below for a number of new features,
improvement and bug fixes:

[libvirt] [PATCH] Fix QEMU p2p v2 migration when run from a v3 client
by Daniel P. Berrange
When peer-2-peer migration was invoked by a client supporting
v3, but where the target server only supported v2, we'd not
correctly shutdown the guest.
* src/qemu/qemu_migration.c: Ensure guest is shutdown in
v2 peer 2 peer migration

[libvirt] [PATCH] qemu: Parse current balloon value returned by query_balloon.
by Osier Yang
Qemu once supported following memory stats which will returned by
"query_balloon":
stat_put(dict, "actual", actual);
stat_put(dict, "mem_swapped_in", dev->stats[VIRTIO_BALLOON_S_SWAP_IN]);
stat_put(dict, "mem_swapped_out", dev->stats[VIRTIO_BALLOON_S_SWAP_OUT]);
stat_put(dict, "major_page_faults", dev->stats[VIRTIO_BALLOON_S_MAJFLT]);
stat_put(dict, "minor_page_faults", dev->stats[VIRTIO_BALLOON_S_MINFLT]);
stat_put(dict, "free_mem", dev->stats[VIRTIO_BALLOON_S_MEMFREE]);
stat_put(dict, "total_mem", dev->stats[VIRTIO_BALLOON_S_MEMTOT]);
But it later disabled all the stats except "actual" by commit
07b0403dfc2b2ac179ae5b48105096cc2d03375a.
libvirt doesn't parse "actual", so user will always see a empty result
with "virsh dommemstat $domain". Even qemu haven't disabled the stats,
we should support parsing "actual".

[libvirt] Building on Solaris 11 Express
by Richard Laager
I would really like to use ZFS's zvols as storage for my guests. I
really like ZFS's snapshots, send/receive, and checksumming features.
(Compression and deduplication might be useful as well.)
I'm roughly about half-way done writing a ZFS storage backend for
libvirt. It behaves like the LVM backend. I've been writing it on Linux.
However, ZFS on Linux is not yet production-ready.
So I tried building libvirt on Solaris 11 Express. The following
outlines the trouble (and successes) I've had so far.
First, I had to prune down the features being built:
I added --without-xen to deal with the following. I wasn't
intending on using Xen, so this doesn't bother me personally.
configure: error: You must install the Xen development package to compile Xen driver with -lxenstore
I added --without-openvz to deal with the following. Likewise,
I'm not using it.

I added --without-network to deal with the following. I may need
to actually fix this at some point.

util/bridge.c: In function `brGetInterfaceUp':
util/bridge.c:652: error: `SIOCGIFFLAGS' undeclared (first use in this function)
Then, I had to fix a trivial code error. I've mailed the patch to this
list with a subject of "[PATCH] Fix virExecWithHook Prototype".
I also had linker trouble. Solaris 11's gcc package uses Solaris ld, not
GNU ld. I had to change the following:
VERSION_SCRIPT_FLAGS=-Wl,--version-script=
`$LD --help 2>&1 | grep -- --version-script >/dev/null` || \
- VERSION_SCRIPT_FLAGS="-Wl,-M -Wl,"
+ VERSION_SCRIPT_FLAGS=""
Interestingly, this code seems to have been added to support Solaris ld
according to git blame; see git log c2fb8bfe. I'm not sure what is
correct here.
At this point, libvirt builds and installs. I tested virsh against a
remote system using: virsh -c qemu+ssh://REMOTE/system
This worked except for the fact that it was trying to attach
to /usr/local/var/run/libvirt-sock on the remote system due
to /usr/local being the --prefix used with the *local* virsh was built.
I'm not sure how that architectural issue should be addressed. For
testing, I just made a /usr/local/var -> /var symlink on the remote
system.
However, libvirtd will not start locally (on Solaris) which has pretty
much stopped my progress. I'm sure this must be something trivial. Is it
getting a bad prefix? Is something other than libvirtd supposed to make
the socket file? I did try making a /.libvirt directory for testing.
# rm /usr/local/var/run/libvirtd.pid ; /usr/local/sbin/libvirtd -v
20:13:33.663: 1: info : libvirt version: 0.9.1
20:13:33.663: 1: error : qemudListenUnix:605 : Failed to bind socket to
'@//.libvirt/libvirt-sock': No such file or directory
