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

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Ahmed,

  Looks like you have not read my the most recent messages to xen-user list.
Xen 3.2.1 /usr/bin/pygrub has a minor bug (on 64-bit), which is supposed to be
fixed, on 32-bit it should work fine without any manual intervention.
Please, view the final draft at :-

Thanks.
Boris

Thanks Boris, this is so helpful.  Currently I can create domains with virt-install, after I shutdown these  domains I still can see them by the "xm -list" command. However, when I  edit a new config file and save it to "/etc/xen" and use the command "xm  create <config file>" the guest appears successfully. However, after I  shut it down, I cannot see it with "xm-list" Ahmed   Boris Derzhavets wrote: > 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.
