Re: [Xen-users] virsh -c xen:/// list: = Connection refused, Set up Xen 3.4.2 & Libvirt 0.6.1 on top of Ubuntu 9.04 Server

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Funny, virt-manager appears responsible , to work  as :-
1. virsh list
2. virsh start/stop <DomainName>
Plus
   # vncviewer localhost:0
via terminal session.

Following your suggestions (except 1)  :-

1. Made direct port Xen 3.4.2 to Ubuntu Jaunty Server & applied ext4 patch for pygrub from Mark Johnson (MRJ)
2. Edited xend-config.sxp
   (xend-http-server yes)
# service xend restart
# ln -s /usr/local/bin/pygrub  /usr/lib/xen-default/bin/pygrub
# apt-get install virt-manager libvirt-bin kvm
# export VIRSH_DEFAULT_CONNECT_URI="xen:///"
# apt-get install virt-viewer

root@ServerJaunty:/usr/lib/xen-default/bin# virsh -version
Connecting to uri: xen:///
0.6.1

Proceed with virt-install :-

 root@ServerJaunty:~# virt-install -n VM12F -r 1024 -p --vnc --noautoconsole \

Domain installation still in progress. You can reconnect to
the console to complete the installation process.

# vncviewer localhost:0
brings up VNC console for F12 installation.

Manging this way

1. I didn't have any problems with prevu build Debian's Xen 3.4.1 to get deb packages.
2. Version of Xen is up to date
3. MRJ's ext4 patch for pygrub may be easily applied.
4. Virt-install works in --noautoconsole mode, creating DomUs.

However , virsh doesn't seem to be completely functional in
regards of managing domains.

# xm start VM12F
# vncviewer localhost:0

starts domain

Actually, i get only working virt-install. Virsh is almost useless
