I am having problem in guest creation for a pv-ops Dom0 kernel I compiled every thing from scratch.(Xen and 2.6.32.27 pv-ops dom0 kernel) on a Ubuntu Desktop 10.04 64 bit. Following is my config file for 2.6.32.27 http://pastebin.com/AvSVgVQE and the error I am getting trying to create a guest with virt-install is ERROR unable to connect to 'localhost:8000': Connection refused Traceback (most recent call last): File "/usr/bin/virt-install", line 943, in <module> main() File "/usr/bin/virt-install", line 715, in main conn = cli.getConnection(options.connect) File "/usr/lib/pymodules/python2.6/virtinst/cli.py", line 162, in getConnection conn = open_connection(connect) File "/usr/lib/pymodules/python2.6/virtinst/cli.py", line 177, in open_connection open_flags) File "/usr/lib/python2.6/dist-packages/libvirt.py", line 111, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: unable to connect to 'localhost:8000': Connection refused I am able to see xm info output but some how the guest creation is failing. I could be wrong, but this doesn't appear to be a kernel problem. Especially if xm info is working, so the xen service has started already. Maybe my libvirt version doesn't know how to use the xen 4.0 utils or the pvops kernel? I tried creating a guest by virt-manager also which when installed via apt-get install ubuntu-virt-server ubuntu-virt-mgmt installs following http://packages.ubuntu.com/lucid/<http://packages.ubuntu.com/lucid/lib... ubuntu-virt-server http://packages.ubuntu.com/lucid/<http://packages.ubuntu.com/lucid/lib... ubuntu-virt-mgmt Now when I open virt-manager the option to create guest by installing from a ISO present on hard disk locally or even PXE are greyed out.virt-manager version is 0.8.2 virsh version Compiled against library: libvir 0.7.5 Using library: libvir 0.7.5 Using API: QEMU 0.7.5 Running hypervisor: QEMU 0.12.3 This above output is wrong as instead of QEMU it should show Xen. I installed it via apt-get install libvirt-bin when you do an apt-get install libvirt-bin python-libvirt then it installs following http://packages.ubuntu.com/lucid/libvirt-bin http://packages.ubuntu.com/lucid/python-libvirt It appears it is a problem with libvirt-bin and it does not know how to create a pv-ops Dom0 guest. The machine where I am trying all this is a non VT 64 bit machine and trying to create 32 bit guests on it. Can some one confirm me the same or tell what did I missed in above? -- http://mightydreams.blogspot.com
