[Xen-devel] Upstreaming Debian patches for Xen Qemu DM

[Thomas Goirand <thomas@xxxxxxxxxx>]

Hi,

For the moment, I'm using these 5 patches for Xen Qemu in my package.
The most important part is the Audio subsystem that by default is not
working. Would anyone care applying them to the Git?

Also, it's been MONTHs since I'm calling for a sponsorship for the first
upload in Debian (I'll manage later updates thanks to the
Dm-Upload-Allowed field). Samuel, Ian, aren't you interested in
sponsoring this one?
