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 programs:

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 after a deeper look into the scene,

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 using a configuration line that looks something like disk = [

-----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. Peter -----BEGIN PGP SIGNATURE----- Version: GnuPG

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. Signed-off-by: Wei Kong <weikong.cn@gmail.com>

Hi all, Has anyone used gdb to debug tapdisk problems? I''ve implemented a custom tapdisk interface and I''m trying to debug a few kernel paging crashes. -Jack

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.

Hi, For this issue I had initial discussion thread before, more detail, please see : http://lists.xensource.com/archives/html/xen-devel/2010-04/msg01140.html. I write a new patch for this issue, which modified qemu code. So Ian, could you take a look this patch,too. thanks, James (Song Wei) Signed-off-by: James ( Song Wei ) <jsong@novell.com> diff -r efa1b905d893

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. *When using tap:aio:* PATH/disk.img in domU disk configuration, the boot process hanged at a prompt: XENBUS:
