Re: [Xen-users] Problem with tap:aio

Hi
No, it did not work. I did: ln -s /usr/lib/xen-3.2-1/bin/* /usr/sbin/
and restarted xend and that domU, but the same errors remain.
Thanks Gemes.
Ok I've checked back how I did. I've modified the xen-utils-common
package, to include symlinks for tapdisk and blktapctrl for
../lib/xen-common/bin/xen-utils-wrapper.
So sorry for misinforming you at the first time, please modify your
symlinks to point to: ../lib/xen-common/bin/xen-utils-wrapper
Good Luck!

Hi all
I was reading through Xen 3 user manual and saw this tap:aio
should be used instead of loopback...
Then I came to do that, but I can get it working with
replacing `file' URI's with `tap:aio'.
My OS: Debian Lenny 2.6.26-2-xen-amd64
DomU Xen configuration file:
kernel = '/boot/vmlinuz-2.6.26-2-xen-amd64'
ramdisk = '/boot/initrd.img-2.6.26-2-xen-amd64'
memory = '1024'
root = '/dev/xvda1 ro'
disk = [
'tap:aio:/xen/domains/test1/manu.img,xvda1,w',
'tap:aio:/xen/domains/test1/disk.img,xvda2,w',
]
name = 'test1'
vif = [ 'ip=10.1.1.50,mac=00:16:3E:51:E4:AD' ]

Gave up waiting for root device. Common problems:

- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda2 does not exist. Dropping to a shell!

=========================================
I modprobed the xenblktap module and also googled, but no success.
Thanks for any comment.

With stock lenny packages blktapctrl ad tapdisk are out of your
PATH, you should try to symlink them from /usr/lib/xen-3.2-1/bin/
to /usr/bin or /usr/sbin, may need to restart xend and then try to
load that tap:aio domain again.
Hope that helps.
