Re: [Xen-users] Need an Idiot's Guide to Installing Xen & Libvirt on Ubuntu 10.04

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

No,  virt-manager doesn't work on 10.04.
Just virt-install works with option --connect xen:///  in command line , it's better than nothing. It creates proper entry in xenstore
Variable VIRSH_DEFAULT_CONNECT_URI
    export VIRSH_DEFAULT_CONNECT_URI="xen:///"
is understood only by virsh, so domains from "xm list" may be
started via virsh, but "virsh list" is empty.

At install :
# virt-install --connect xen:///  -n DomName  -r 2048 .  .  .  .
creates PV & HVM DomUs  and relaunches  VNC console.

At runtime :
# xm list
# virsh start DomName
# vncviewer localhost:0

I would remind that "xm new dom.cfg" fails on Ubuntu's.

Obvious regression vs Ubuntu Server 9.10 (libvirt 0.7.0)
Just as Solaris Nevada 3 years ago :)

This could be only partially related at best, but I think virt-manager
also uses libvirt. I remember trying virt-manager on 10.04 and the pvm
would disappear from the manager gui's list right after starting it.  It
would be interesting to see if any of the steps in your guide has a
positive effect on that as well.
