Re: [Xen-users] Simple question about Para-virtualized drivers in Windows

[Alba <florfoto@xxxxxxxxx>]

Thanks Fajar for your reply.
I'm not using Redhat PV drivers on boot disk.

My DomU config file is:

disk = [ "file:PathToMyImage.img,hda,w", "tap:aio:/dev/sda1,xvdb,w" ]

I'm not sure which disk should I use in the Win DomU: if the one that says "QEMU HARDDISK"  or the one that says "RHEL DISK SCSI Disk Device".

Thanks in advance for your help.

Regards,

Alba

What is your domU config like?
Redhat's PV driver should NOT be used for boot disk.
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Para-Virtualized_Windows_Drivers/chap-Para-Virtualized_Windows_Drivers-Requirements_and_restrictions.html

So your disk like should look something like this (old-style config)

disk =  [
       'phy:/dev/VolGroup/disk1lv,hda,w',
       'phy:/dev/VolGroup/disk2lv,xvdb,w',
       ]

Note hda and xvdb, and NOT xvda and xvdb.

Personally I'd recommend you use James Harper's GPLPV (at least for
now), as it's more widely used, and it can be used on boot disk (C:).
You don't need to change any domU disk config with GPLPV.
