Re: [Xen-users] XCP: how to connect to VNC term of new VM (was: VM installation in XCP 0.5 is behaving strangely)

[George Shuklin <george.shuklin@xxxxxxxxx>]

Yes, if vm-start return nothing in reasonable time it sign that all ok
(if not ok it will start to say something like 'pygrub no bootable disk
found", etc).

There is three different way to continue system setup.

First: create preseed/kickstart file. Hard to make from scratches and
postinstall debug.

Second: Access to VNC console via openxencenter. It really not very good
from my point of view, because not working (last time I test it few
month ago) with slave hosts.

Third: my favorite. Create SSH tunnel to localhost: ssh -L
5901:127.0.0.1:5901 -L 5902:127.0.0.1:5092 ... -L 5999:127.0.0.1:5999
root@your-xen-host.

(this command must be run as root). After that you can connect to
vncterm, listening on localhost on XCP host. 

You can found requied VNC port from xenstore:
xe vm-list uuid=vmuuid params=dom-id  (here you got domID for VM)
xenstore-ls /local/domain/<DOMIDFROMLINEABOVE>/serial/0
(f.e. 5904)

... and connect to those port via xvncviewer from your own linux desktop
(you are using linux at you desktop, isn't it?):

xvncviewer localhost:5904 (or other port from xenstore-ls).

Note: every time VM migrating, restarting or stop/starting you must
refound again port number.
