Re: Setting up libvirt to work with Xen 3.4.1 on F11

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Yes, Pasi .
I've changed Xen Host setup as follows ( new clean install):-

Download xen-3.4.1-1.fc12.src.rpm

# wget http://kojipkgs.fedoraproject.org/packages/xen/3.4.1/1.fc12/src/xen-3.4.1-1.fc12.src.rpm
# rpm -iv xen-3.4.1-1.fc12.src.rpm
# cd /root/rpmbuild/SPECS
# rpmbuild -ba ./xen.spec

To install hypervisor and tools

# cd ../RPMS/x86_64
# yum install xen-3.4.1-1.fc11.x86_64.rpm \
xen-debuginfo-3.4.1-1.fc11.x86_64.rpm \
xen-devel-3.4.1-1.fc11.x86_64.rpm \
xen-doc-3.4.1-1.fc11.x86_64.rpm \
xen-hypervisor-3.4.1-1.fc11.x86_64.rpm \
xen-libs-3.4.1-1.fc11.x86_64.rpm \
xen-runtime-3.4.1-1.fc11.x86_64.rpm

To install new libvirt-0.7.0-6

  # cat > /etc/yum.repos.d/fedora-virt-preview.repo << EOF
  [virt-preview]
  name=Virtualization Rawhide for Fedora 11
  baseurl=http://markmc.fedorapeople.org/virt-preview/f11/\$basearch/
  enabled=1
  gpgcheck=0
  EOF

Install Preview version of libvirt :-

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

[root@ServerXen341 ~]# rpm -qa|grep virt
libvirt-client-0.7.0-6.fc11.x86_64
libvirt-python-0.7.0-6.fc11.x86_64
virt-viewer-0.2.0-1.fc11.x86_64
virt-manager-0.7.0-5.fc11.x86_64
libvirt-0.7.0-6.fc11.x86_64
python-virtinst-0.500.0-1.fc11.noarch

It works fine with PV DomUs. 
Attempt to install HVM via virt-manager gives a new error :-

    return self._do_install(consolecb, meter, removeOld, wait)

    if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)

Just to be sure: You are able to install _HVM_ guests using Xen tools?
