Good day.
Im having problems with xen 4.1 in blktap2 operation.
1) can`t attach vhd image with tapdisk2 –n vhd:/path/to/file , application respond with “usage: tapdisk2 <-u uuid> <-c control socket>”, in previous version it was “usage: tapdisk2 <-n file>”. Question is, how to attach image file in xen 4.1 , please ?
 
2)  after stopping domU with tap2:vhd images, tapdisk2 processes remain in memory as well as devices in /sys/class/blktap2.  On other hand, there are no longer possibility to list attached images in /sys/class/blktap2/devices:
sarge@kxen pts/2: cat /sys/class/blktap2/devices
0 €L©
1 €—˜4
2 €wøã
3 €÷9
 
instead of expected (from previous 4.0.1) :
0 vhd:/etc/xen/images/webserver.vhd
how to read currently attached disks please ?
 
 
best regards
 
Rene
