Subject: How to get the real device in guest os after attached a disk?
Date: Tue, 17 Jul 2012 11:40:59 +0800	[thread overview]
Message-ID: <1936723074.42171.1342496460585.JavaMail.hzwangpan@corp.netease.com> (raw)

Hi all,
I have a question as the subject above, the reason I want to know this is that, if I attach some disks on the guest,
for example, I specified /dev/vdc&/dev/vdd(target device) at the cmd line by using 'virsh attach-disk', but they may be /dev/vdb&/dev/vdc in the guest os,
so if the guest user want to detach the /dev/vdb(guest device), he\she will be confused with the two target devices /dev/vdb&/dev/vdc,
because he\she doesn't know the corresponding relation of the guest device and target device, 
he\she may detach an error device /dev/vdd(target device) which corresponding to /dev/vdc(guest device).

Could anyone give me some idea?
Thanks in advance.

Best Regards
Wangpan
