[Xen-users] hot change installation cd HVM OEL

[Alberto Asuero Arroyo <albertoasuero@xxxxxxxxx>]

HI!

I'm trying to install Oracle Enterprise Linux, but the installation asks another install cd. I've tried xm block-detach/ xm block-attach.

I don't have physical contact with the server, only ssh and vnc.

I can attach but no detach.

(Burrows is the name of my domU and burrows's id  is 18)

scofield:/home/alasarr/oel#xm block-attach burrows file:/home/alasarr/oel/Enterprise-R5-U3-Server-x86_64-disc2.iso  ioemu:hdc:cdrom r (works Fine)
scofield:/home/alasarr/oel#


scofield:/home/alasarr/oel# xm block-list 18

scofield:/home/alasarr/oel# xm block-detach 18  832
Error: Device 832 (vbd) could not be disconnected.
Usage: xm block-detach <Domain> <DevId> [-f|--force]

Destroy a domain's virtual block device.

xm log shows:
