Hi John.

Thank you for your support again :)

> Also, what sort of VM are you trying to launch? Is it a three part image with external kernel?
Yes, I use this VM images.
ttylinux-uec-amd64-12.1_2.6.35-22_1
 - ttylinux-uec-amd64-12.1_2.6.35-22_1.img
 - ttylinux-uec-amd64-12.1_2.6.35-22_1-initrd
 - ttylinux-uec-amd64-12.1_2.6.35-22_1-loader

cirros-0.3.0-x86_64-uec
 - cirros-0.3.0-x86_64-blank.img
 - cirros-0.3.0-x86_64-initrd
 - cirros-0.3.0-x86_64-vmlinuz

I'll check use EXT3 local SR and "kpartx" command.

Thanks!
Suzuki

> I think the problem you are hitting is because there was a recent change in XCP/XenAPI where mounting the VDI into dom0 no longer automatically exposes the partitions of that disk to the Dom0 Kernel, so you need to use kpartx (or similar) to mount to appropriate partition. I can see you are hit this because the device returned is "/dev/sm/<guid>/<guid>" rather than "/dev/sda1" or something like that. I got normal VMs working OK despite this, but have not yet gone through all the XenAPI plugins to ensure all the issues are fixed.
