Guest OS installation failed on a logical volume in CentOS 5.1 64bit!
hi,
I got a new 64bit dell server with 6 500GB sata disks.
I have some problem to install Guest OS on CentOS 5.1 64bit Host OS with xen.
I created 2 raid 5 VD(virtual disk), one is 200GB, the other is 2288 GB. When I tried to install centOS5.1 64 bit on the 200GB, the “/”
Always be placed on 2288GB VD (that’s not I want), so I erased both VD and recreated 200GB VD and install host OS on it. Then
Restart server to build second VD 2288GB.
After that I create a volume group on second VD, and create a 500GB logical volume on it.
Following is output from system:

lv2 vg0 -wi-ao 48.81G
lv3 vg0 -wi-ao 46.75G
dev vg1 -wi-a- 500.00G
But when I tried to install GuestOS centOS5.1 on the logical volume , it always broke after formatting and loading files.
Is it because the “dev” logical volume’s Attr is –wi-a-?
Second question is: since this dell server is a 64bit system, so I should use 64bit centos as host os, then install 32bit os as guest os, or doesn’t matter?
Third question is : how to install a comeplete guest OS from a CD?
thanks for your help!
