Can't block-attach a file on a read only volume?
Hi All,
One more weird issue, this works on old xen but fails on 4.4:
xendev01 ~ # mkdir /mnt/test
xendev01 ~ # mount -t tmpfs - /mnt/test
xendev01 ~ # dd if=/dev/null of=/mnt/test/disk seek=100M bs=1
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000201809 s, 0.0 kB/s

Incorrect shell quotation in scp
Hi,
as the current debian maintainer of the openssh package is a bit busy,
I'm helping him with fixing a part of the bugs in openssh that debian
users found will forward some of the reports to you. This is the first
one and a fix or a comment why this should not be fixed would be
appropriated. Thanks
Space in filename is not correctly passed by scp to other invoked

A little confusion between "tapdisk" and "tapdisk-ioemu"
Hi everyone,
as what I''ve learned form this link<http://wiki.xensource.com/xenwiki/blktap>,
i know that when i specify tap:aio I’m actually using the blktap driver and
finally using "tapdisk" to wirite to raw image file.
but the truth is even when i delete /usr/sbin/tapdisk the domU can still
boot on my machine with tap:aio protocol

libxl device_disk_add orphans blktap devices on transaction error
I''m using the CentOS 6 bundle of xen from
http://dev.centos.org/centos/6/xen-c6/ and ran into an issue when
creating domains with multiple VHD tap disks. Comparing unstable to
the 4.2.1 code I''m using, it seems this issue still applies. I''m

RFC: add tapdisk link in xen-common for blktap
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
while trying to get blktap based domus running with current Debian Xen
3.1.2 I came across a missing link: The tapdisk binary should be added
to GLOBAL_SCRIPTS in xen-common/scripts/Makefile. Otherwise blktap
based domus don't find their disks. blktapctrl forks tapdisk processes.

[PATCH] tapdisk:check O_DIRECT on hole file for performance
Although tapdisk has been instead of tapdisk-ioemu, but it still used on
some old xen-3.2.
So fix a performance problem here.
--
Kernel aio will retry when encounter a block doesn''t allocated, then do
async io,
but O_DIRECT flag was there, so io_wait on sync data.
And clean a little code style.

Attaching GDB to Tapdisk for Debugging

[PATCH] blktap: Automatically start tapdisk-ioemu on demand
When a domain wants to use a tap:ioemu disk but has no device model,
start a tapdisk-ioemu instance as provider. Also, move the creation and
removal of communication pipes to xend so that qemu-dm doesn''t need the
unwanted SIGHUP handler anymore.

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.

Continued utmp probs with sshlogin.c
Hi all,
I've hacked in some better logging for what's going on with my logins and
utmp/wtmp. Everything seems OK except for u.ut_host.
In my case, the actual variable host for this test case is
aragon.cheshirelaw.com. This is fine (as my logs show):
