I believe qemu installation was skipped

Pasi,

I was able to install 3.4.1 Hypervisor via xen-3.4.1.src.rpm with no problems.
Rebooted into Xen Host with 2.6.30.3 xenified aka Suse kernel. Fine.

Downloaded from http://markmc.fedorapeople.org/virt-preview/f11/x86_64/
and installed (pretty recent - 08/10/2009) :-

yum install libvirt-0.7.0-3.fc11.x86_64.rpm \      
libvirt-client-0.7.0-3.fc11.x86_64.rpm \
libvirt-devel-0.7.0-3.fc11.x86_64.rpm \
libvirt-python-0.7.0-3.fc11.x86_64.rpm \
python-virtinst-0.500.0-1.fc11.noarch.rpm \
virt-manager-0.8.0-1.fc11.noarch.rpm \
virt-viewer-0.2.0-1.fc11.x86_64.rpm

[root@ServerXen341F Download]# rpm -qa|grep virt
libvirt-0.7.0-3.fc11.x86_64
libvirt-devel-0.7.0-3.fc11.x86_64
python-virtinst-0.500.0-1.fc11.noarch
virt-manager-0.8.0-1.fc11.noarch
virt-viewer-0.2.0-1.fc11.x86_64
libvirt-python-0.7.0-3.fc11.x86_64
libvirt-client-0.7.0-3.fc11.x86_64

Then i was able to connect to xend via virt-manager and attempted to start building
OSOL HVM. Got an error at startup:-

Unable to complete install '<class 'libvirt.libvirtError'> Domain not found: xenUnifiedDomainLookupByName
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/create.py", line 1489, in do_install
    dom = guest.start_install(False, meter = meter)
  File "/usr/lib/python2.6/site-packages/virtinst/Guest.py", line 628, in start_install
    return self._do_install(consolecb, meter, removeOld, wait)
  File "/usr/lib/python2.6/site-packages/virtinst/Guest.py", line 726, in _do_install
    self.domain = self.conn.createLinux(install_xml, 0)
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1077, in createLinux
    if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)
libvirtError: Domain not found: xenUnifiedDomainLookupByName

Please advise , how to escalate it to Fedora's people ?

Boris.
P.S. Usually i installed libvirt stuff :-

# yum install libvirt libvirt-python python-virtinst \
virt-manager virt-viewer

To apply patch manually i need a kind of libvirt.src.rpm.
I don't track Fedora so close to be aware of this.

I grabbed Xen 3.4.1-1 src.rpm from:
http://kojipkgs.fedoraproject.org/packages/xen/3.4.1/1.fc12/

and rebuilt that for F11.

The next problem was that libvirt package in Fedora 11 has a bug, which causes it
to crash (segfault) when virt-viewer is started. This crash only happens with Xen 3.4, not with Xen 3.3.

Patch for the libvirt bug is here:
http://libvirt.org/git/?p=libvirt.git;a=commit;h=14435163a086c0bcdff04308077fa46a5fa08bb0

Upcoming libvirt update for F11 will fix this. After manually applying that
patch and rebuilding libvirt I'm now able to successfully install new guests
using virt-install and connect to their console by virt-viewer.
