Everything seems to run fine, except that I am trying since a few hours=20 to mount a .vhd file in the dom0. What I tried so far: to create a blank vhd file (this is working): host# vhd-util create -n /storage/test.vhd -s 20G Then i try to mount the file in dom0 (as stated in a blktap2 README file) host# tapdisk2 -n vhc:/storage/test.vhd it fails, returning: tapdisk2: invalid option -- 'n' usage: tapdisk2 <-u uuid> <-c control socket> Then i've tried: host# tap-ctl list It returns: blktap kernel module not installed Then tried too: host# xl block-attach 0 tap:vhd:/storage/test.vhd xvda w 0 It does not complain but nothing happens. Am I getting something wrong about how to do it ? Does the 3.0.0-rc5=20 kernel is missing something ? (look like there is no blktap module in the kernel tree, but blkback=20 that I enabled, don't know if it's the same) I have no more ideas about what to try next. Any clue ? Thanks a lot for your help! Kind regards, S=E9bastien
