Re: [Xen-users] Ubuntu: DomU hangs on boot
|
It could be you ran out of ram, i see you only have
383, try reducing the xen to use 64 and see how that goes, Also be quick in
going to xm console xenname it could be freezing on something when it
boots

Subject: Re: [Xen-users] Ubuntu: DomU
hangs on boot
To clarify:
After I issue the "xm create xen_domu_name"
command, no errors are returned, and the "xm list" command shows something
like
this:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Name
ID Mem VCPUs State
Time(s)
Domain-0
0 239 1
r-----
279.0
xendomu
7 128 1
-b----
27.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
However, I am unable to ssh
into the VM, and typing anything at the "xm console" screen yields no
response. (Though, the "xm console" does show the scroll back listed
below.)
Also, here is the output of "xm
info":

Hello,
I
followed the directions
at:
http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories
Dom0
boots fine.
However, I can't seem to get any DomU to
start.
Any help would be appreciated.
Thank
