[Xen-users] HVM domain can not boot up with Qcow incremental image
Dear,Beg for your help. I am really puzzled with this problem.HVM domain can not
boot up with Qcow incremental image(using command: qcow-create size
incremental_file original_Qcow_img_file), but it can boot up with the original
Qcow disk image file. When using Qcow incremental image, the guest qemu window
would disappear before loading grub, and `xm list` can not find this guest
domain.The VM screen shows some information:……HVMAssist BIOS, 1 cpu,

Re: [Xen-users] HVM domain can not boot up with Qcow incremental image

You could probably try: - update to xen 4.0.0 - use vhd instead of qcow: http://lxr.xensource.com/lxr/source/tools/blktap2/README you could use packaged xen 4 from Gitco, but if you want to use blktap2+vhd you''d need a newer kernel, which AFAIK is not available as binary package for Centos (yet). Try http://lists.xensource.com/archives/html/xen-users/2010-07/msg00452.html if you want to use the version that I use (you need to build the RPM yourself from the provided SRPM, and it''s only tested on x86_64). -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
