[virt-tools-list] RHEL 6 virt-install 64 bit host, 32 bit guest



I am trying to create a virtual machine on a 64 bit RHEL 6 machine.  There are 4 processors on the host and 24G of RAM.  I will be running an old version of redhat 7.3 as the guest o/s.

 

I am installing rh7.3 from a mkcdrec CD that I have used to install many other times, so the CD is good.

 

The command I use to create the VM is:

virt-install --connect=qemu:///system --name=rh73 --hvm --ram=1024 --vcpus=1 --disk path=/opt/vm/rh73.img,size=2 --network bridge=br0 --vnc  --vncport=5962 --noautoconsole  --os-type=linux  --os-variant=generic24  --cdrom /dev/cdrom

 

The first problem I encounter is during the un-tar of the o/s.  I get messages like:

tar: ./usr/X11R6/bin/cleanlinks: Wrote only 0 of 10240 bytes

tar: Skipping to next header

tar: Archive contains obsolescent base-64 headers

./usr/X11R6/bin/bmtoa: Wrote only 0 of 10240 bytes

tar: skipping to next header

./usr/X11R6/bin/dga

tar: ./usr/X11R6/bin/dga: Wrote only 0 of 10240 bytes

tar: Skipping to next header

 

When I rebooted the guest o/s, it gave a kernel panic.  Upon further examination the /etc/fstab file was 0 bytes.  I booted the guest o/s from a recovery CD.  I ensured the root file system was mounted read-write.  I vi’d the fstab file and added the file systems, but it would not save the changes.  So I echo’d the file systems into that file and still it would not save the changes.

 

I am not sure what’s going on with the fstab file and it not letting me edit that file.

 

Is it possible these errors are indicative of trying to install a 32 bit o/s under a 64 bit host?  I tried using the --arch option of the virt-install command, but I haven’t found the magic combo to get it to recognize that option yet.

 

Any insight you can give on what’s going on here, or how I can fix it would be appreciated.
