[Xen-users] Ubuntu 11.04 DomU not showing external block Device
Hello,
I just installed Xen 4.0.1 on Ubuntu 10.04 dom0. After this i had
Ubuntu 11.04 as Para domU.
I tried to attach file based disk to the this domU.
My command is:
# xm block-attach Ubuntu-11 file:/root/ubunut-natty/Extra
/dev/xvdb w
there is no error on this.
But inside the DomU i cannot see any disk xvdb.
xend.log shows :
[2011-10-25 16:27:32 14794] DEBUG (XendDomainInfo:853)
XendDomainInfo.device_create: {''uuid'':
''18743cdb-d88a-84e3-c2e4-c5c726e06cda'',
''bootable'': 0, ''driver'':
''paravirtualised'', ''dev'':
''/dev/xvdb'', ''uname'':
''file:/root/ubunut-natty/Extra'', ''mode'':
''w''}
I tried googling !! Any Ideas??

Thanks

Florian -- the purpose of libvirt is to provide an abstraction layer hiding all xen features added since 2006 until they were finally understood and copied by the kvm devs.

|does it show as mapped in xm block-list afterwards? When the disk is attached it doesn''t throw error.. I think the device gets mapped, but not sure , i will check out. | will the same disk be visible in the domU after a reboot (launched from inside)? | will it be visible once you add it to disks = [] ? This two things i need to check , i will get back with the details...
