[Xen-devel] [XCI] set up a paravirtualized VM

[Kornelius Prell <kornelius.prell@xxxxxxxxxxxxxx>]

Hello,

 

in the last days I've built Xenclient and successfully created a Windows VM according to

Takas mail here: http://lists.xensource.com/archives/html/xen-users/2009-06/msg00276.html

 

Now I was wondering what it takes to set up a paravirtualized VM in Xenclient.

I tried to boot my Debian Lenny system (with Xen [2.6.26-1-xen-686] kernel / initrd and Xenclient kernel / initramfs) as a pv VM without much success.

It is initalised in paused state and unpausing it won't help (it gets into running state but top shows completly idle CPU).

 

I cannot find any error in the /tmp/xenvm-debug logfile so far:

Here is the VM config file:

uuid = 01000000-0000-0000-0000-102130000014
hvm = false
memory = 1024
debug = true
kernel = /boot/vmlinuz
initrd = /boot/initramfs.gz
disk = /dev/sda:phy:hda:w:disk
cmdline = root=/dev/sda1 ro
boot = c
vif = bridge=xenbr0

 

Is there a possibility to fetch the log of the boot process of a paravirtualised guest VM?

 

Thanks

Kornelius
