xen 4.1.1 + 3.0.0-rc5 dom0 + blktap2
Hi,
I''m currently trying xen 4.1.1 with the 3.0.0-rc5 (heard that it now
contains the xen code to run as front or back xen domain).
Everything seems to run fine, except that I am trying since a few hours
to mount a .vhd file in the dom0.
What I tried so far:
to create a blank vhd file (this is working):
host# vhd-util create -n /storage/test.vhd -s 20G
Then i try to mount the file

Mounting filesystems with blktap2
For those wanting to know how to mount filesystems through blktap2
here is how you do it, as I couldn''t find it fully documented.
The instructions on the blktap2 readme file are rather out of date.
You can mount them under Dom0 like so.
e.g. to mount a vhd file,
sudo xm block-attach 0 tap2:vhd:/home/xen/xenwin7-persist.vhd xvdb w 0
Now the device should appear under /dev

Xen 4.0.1, tap vs tap2, blktap2 documentation, and gentoo-xen-kernel problem
Hi,
I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 +
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-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

I''m getting this message (subject line) in daemon.log every time I

that I cannot boot up my Windows domU from a VHD file. The Windows

When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can

domU can not start in Xen 4.0.1-rc3-pre using tapdisk
The domU is using pygrub to boot its own 2.6.18.8-xen kernel. It can be
booted successfully under 2.6.18.8-xen dom0 and xen 3.3.1.
However when upgrade dom0 to 2.6.32.15 and xen 4.0.1-rc3-pre, the domU can
not boot with tapdisk. I am wondering it is something related to the blktap
driver.
