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

Livelock induced failure in blktap2.
We''ve been working on getting XEN 4.1.2 validated for internal use and
have run into what appears to be a livelock induced failure in
properly freeing a blktap2 device.
We ported the blktap2 driver from Dan Stodden''s GIT tree into 3.2.x
which is a reasonably straight forward process. We are also running
the toolchain with a patch which Ian Campbell posted in order to get

Problem importing virtual disk
Hi. Let me know if I should be reporting this elsewhere for reasons that I''m about to detail below.
I''m fiddling with Xen 4.1.1 on Debian squeeze running kernel 3.0. I was really exciting about the Kronos project bringing the API to Debian/Ubuntu so I thought I''d give it a try.
I''m find myself facing a number of challenges working with a local lvm based SR.

Errors of doing "make install-tools" with xen-4.2-unstable?
Hi,
When I do the "make install-tools" with xen-4.2-unstable, there are some
errors about "warn_unused_result".
Is it the error in code or the error in the compiling environment? Thank
you so much.

How to install pv guests with tap2:aio for remus
Hi Guys,
I''m working with:
1. xen 4.1;
2. dom0 ubuntu kernel 3.2
I''m trying to run remus with disk replication (I can run without disk
replication). But I read I need to use tap2 <
http://nss.cs.ubc.ca/remus/doc.html>.
Well... first I tried to create a pv guest. Then I take this guest.cfg:

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The instructions on the blktap2 readme file are rather out of date.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

Tapdisk processes being left behind when hvm domu's migrate/shutdown

A fair few things under tools link against libraries which they don''t
even use.
Most of this appears to come from copy-and-pasting previous Makefile

Remus blktap2 issue
Hello,
I have been playing around with Remus on Xen 4.0.1, attempting to fail-over
for an HVM domU.
I''ve run into some problems that I think could be related to tapdisk2 and
its interaction with how one sets up Remus disk replication in the domU
config file.
A few things I''ve noticed:
