[Xen-users] Virt-install and pygrub (bootloader)

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Creating same PV DomU at Xen 3.1 F8 Dom0 works fine.
"xm list -l" reports that bootloader for PVM is /usr/bin/pygrub.
Native pygrub on F8 Dom0 and pygrub compiled from source
at Xen 3.2.1 F8 Dom0 have different lengths.I didn't run "diff" to get details.
My guess is:-
Virt-install creates image specific for "pygrub" bootloader - that is a root cause of issue. DomU create by virt-install from "python_libvirt" (F8 repos) is expecting native pygrub bootloader to be managed properly by "xm"
When you try to do that at Xeb 3.2.1 Dom0 another ( not native) pygrub  appears to  be invoked as bootloader and it doesn't work.
I also don't know how many python executables scripts might  be invoked
when " xm start <Domain>" is issued.
That is my inderstanding of the mess you've got after install "python_libvirt" from F8 repos. Actually, for hard core xen developer
it shouldn't be a mess , but virt-install at Ubuntu 8.04 Dom0 (2-6.24-17-xen) is comletely useless at mean time.

It worked, Thanks Alain.

However, I still have further problems:

1- I still cannot get "Virtual Machine Manager" to work, I feel it is
another configurations problem
*****************************************************
Actually, one doesn't need virt-manager to manipulate
with Domains created
 by virt-install (like on
 Nevada)
xm start <Domain>
xm shutdown <Domain>
xm console <Domain>
xm reboot  <Domain>
All this commands hangs with PV CentOS 5.1 DomU
at Xen 3.2.1 F8 Dom0 (64-bit). 
DomU has been successfully created with 
virt-install installed from F8 repositories
************************************************
2- I created a domain using the "xm create <domain name>" then
I just shut
it down. When I do "xm start <domain name>" it says
"<domain name> does
not exist". How can I get xm to recognize previously created domains.

3- How can I see the Xen logs from Dom-0. Where are they saved? Is there a
specific toold to see events that occur in the hypervisor during the real
time?
