tap:aio problem on Xen 3.4.3-rc7-pre

[Fantu]

Dom0 Lenny 64 bit with kernel
linux-image-2.6.32-5-xen-amd64_2.6.32-12_amd64.deb and xen from hg-testing
DomU windows xp with gplpv_XP_0.11.0.213_debug.msi

Starting domU with tap:aio (my default option config in all production
system) gives always blu screen and i solved only changing disk from
"tap:aio" to "file"
Here the log file with tap:aio disk and problem: 
http://old.nabble.com/file/p28526121/qemu-dm-CORSO01.log qemu-dm-CORSO01.log 

Can somebody help me solve problem for continue use tap:aio and also xen
3.4.3?

Could it have something to do with QEMU...

Because I noticed:

-QEMU_TAG := xen-3.4.3-rc6
-


Without a new QEMU_TAG being added.

More likely a misconfigured dom0 kernel. It would be easy to check whether
it works with xen-3.4.3-rc6, or tip of 3.4-testing with the QEMU_TAG added
back in...

thanks for aswer, module blktap is active, what i do for build/install from
tags? now i do only hg clone, and for update xen installed i must do make
uninstall and after make install...?
for this install i have do only:
make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom
is ok?
and if i make uninstall delete also any kernel from package with "xen" in
name but not pv_ops installed with xen (without "xen" in name)

this is the config of debian kernel used, there are config how do problem? 
http://old.nabble.com/file/p28535906/config-2.6.32-5-xen-amd64

Re: tap:aio problem on Xen 3.4.3-rc7-pre

[Keir Fraser]

In a previous message you said your logs contained "BLKTAPCTRL[2795]:
blktapctrl_linux.c:92: couldn't find device number for 'blktap0'". This
indicates the tools looked for blktap0 information in
/sys/class/xen/blktap0/dev and /sys/class/misc/blktap0/dev and found it in
neither place. Which would indicate something is missing or wrong with the
dom0 kernel setup. Xen and tools should not need rebuilding to fix this.

Re: tap:aio problem on Xen 3.4.3-rc7-pre

[Keir Fraser]

I'd try configuring blktap into the kernel (CONFIG_XEN_BLKDEV_TAP=y), rather
than as a module.
