When i xl-create a guest, i get one message per assigned block device:
root@xenturio1:/var/log# xl create /etc/xen/domains/x1test.sxp
Parsing config file /etc/xen/domains/x1test.sxp
Daemon running with PID 8704
root@xenturio1:/var/log# tail -10 error |grep SYMLINK
syslog:Jul 22 10:58:05 xenturio1 udevd[8658]: kernel-provided name
'blktap2' and NAME= 'xen/blktap-2/blktap2' disagree, please use
SYMLINK+= or change the kernel to provide the proper name
syslog:Jul 22 10:58:05 xenturio1 udevd[8664]: kernel-provided name
'blktap3' and NAME= 'xen/blktap-2/blktap3' disagree, please use
SYMLINK+= or change the kernel to provide the proper name
The guest works fine at that point.

[blkback.3.xvda1]
root 9068 0.0 0.0 0 0 ? S 11:00 0:00
[blkback.3.xvda2]
Then i shutdown the guest:
root@xenturio1:/var/log# xl shutdown x1test
And i am left with remaining tapdisk2 and udev processes, one for each
block device that was assigned to the guest:
root 8975 0.1 0.0 21664 3256 ? SLs 11:00 0:00 tapdisk2
root 8981 0.0 0.0 21664 3256 ? SLs 11:00 0:00 tapdisk2
root 8983 0.0 0.0 21008 796 ? S 11:00 0:00 udevd
--daemon
root 9002 0.0 0.0 21008 800 ? S 11:00 0:00 udevd
--daemon
I am using Xen 4.1.1 with the 2.6.32.43-pvops kernel from jeremy.
My distro is debian 6.0.2. that uses udev 164-3.
I did update it on a different machine to 171-3, but that did not help.
My xen-backend.rules contains the default:
SUBSYSTEM=="xen", KERNEL=="blktap[0-9]*", NAME="xen/blktap-2/%k",
MODE="0600"
SUBSYSTEM=="blktap2", KERNEL=="blktap[0-9]*", NAME="xen/blktap-2/%k",
MODE="0600
My questions are:
- Are the two issues related?
- How can i fix them?
I think that eventually this will cause the host to run out of either
free process IDs and/or RAM.
