Xen kernel on Debian Wheezy

Hello,

I installed Debian 6 from the linode manager and updated it to the frozen testing repository (Debian Wheezy). Now, i need some specific kernel modules such as soundcore to create a virtual Alsa loopback device. As far as i can see, there is no linux-image-xen-amd64 package in the wheezy repositories. Instead, the description of linux-image-amd64 reads that it should also work on a xen hypervisor.

When following the tutorial in the linode library, i get the following error message multiple times after a reboot: > Failed to read /local/domain/0/backend/vbd/1039/51712/feature-flush-cache.

Also, my partition is being detected as ext2fs, en due to several other errors during the bootup process, the filesystem is sometimes mounted as read-only and sometimes not. Do i have to enable something specifically in order to let the xen hypervisor support of my kernel work? Or isn't it possible to accomplish my goals this way?

Thanks in advance,

Leonard
