Re: [Xen-users] Upstream QEMU does not support vhd snapshot

Hi  Thanos,

 

     Thank you for your reply.

     I applied this patch to xen 4.3.0-rc6, and make tools; make install-tools;  and then reboot the system.

     However, snapshot created by vhd-util still cannot be mounted by qemu.

     I doubt whether there are other problems here.

AFAIK there isn't any, but you could try applying the fix that exists in blktap2.5: https://github.com/xapi-project/blktap/commit/a79ac2c05f97c2384bbf981419f329f184dc646a. It shouldn't be very hard to rebase the patch.

 

Cheers
