...-2.6.34-4.tar.bz2, and one of the things that I noticed immediately is there are two problems with tapdisk and this combination. First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works. When tested with HVM domU, it boots, but there was no disk attched (and /sys/class/blktap2/devices stays empty). Changing it to tap2:tapdisk:aio works (sort of). I recall some discussion about tap vs tap2 compatibility on this list earlier, but no final conclusion. Shouldn''t newer versions be backward compatible? Existing tap:aio and tap:tapdisk:aio should just work to minimize...

Hey! As I''ve already written about two days ago, I''m having major trouble getting blktap2 to work properly. After trying xen-sources-2.6.32-xen-r1 from Gentoo (where Andrew Lyon, the maintainer, has already confirmed that he''s hitting the same problem as me, i.e. the blktap2 driver is dysfunctional in the kernel), I decided to give a pv_ops-Kernel a try, and checked out and com...

...the source with make && make install, no problem, but it seems I also need the kernel driver. I''ve tried both 2.6.31.13 and 2.6.32.11 and none has the config TAP2 option, only the TAP. It depends on something to be seen? Or maybe is in another version of the kernel? How can I try blktap2 please...

...so good. I previously used "tap:aio" to link in the hard disks of the domUs: disk = [ ''tap:aio:/var/xen/domains/myhost/swap.img,sda1,w'', ''tap:aio:/var/xen/domains/myhost/disk.img,sda2,w'' ] After some research, I see that the successor "blktap2" is not available as a Debian package (see http://j.mp/dK59hn). What is the recommended way of linking in hard disk images in Debian 6? I am aware you can use "file:", but this has not been recommended since Debian 4. Alternatively, are there any unofficial repositories with pac...

What doesn't work: - Using virt-manager to install PV domUs using file images as storage (tap:aio backend). This libvirt/blktap2 file images failure with Xen 4.4 rpms is a regression from Xen 4.2 rpms, where blktap2 works OK with libvirt/virt-install/virt-manager. The problem is most probably the fact that we had custom patches included in the xen4c6 libvirt rpms that we shipped with the Xen 4.2 rpms. We had to add two pat...
