Re: [Xen-users] Ubuntu: DomU hangs on boot

[Allen Fowler <allen.fowler@xxxxxxxxx>]

*bump*

Has anyone been able to get Xen working from the Ubuntu Gutsy repos? 

Or, am I just doing something wrong?

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,

Mitch,

Hmm.. OK i tried allocating 64MB of ram, but the results are the same.


Here is what xen list shows then:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   239     1     r-----    417.5
xendomu                                   10    64     1     -b----     11.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 Also be quick in going to xm console xenname it could be freezing on something when it boots

I can see the backlog when I type xen console, I just can't type anything there.  See log attached below in original message. (Is that what you meant?)

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 you,
Allen
