RE: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

HVM configuration has been changed. “cdrom” item is removed and merged into disk item. You can follow /etc/xen/xmexample.hvm to modify your HVM configuration.

The new cdrom usage should like:

disk = [ 'file:/var/images/install.img,hda,w', 'file:/root/installimages/winxpsp2.iso,hdc:cdrom,r' ]

Subject: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006

 

I grabbed the unstable download from 9-7-2006.

 

When I go to create a hvm VM, I get a CDROM boot failure code: 0002 in xm dmesg.

 

In my configuration file, I have tried the following:

 

cdrom=/dev/had

cdrom=/root/installimages/winxpsp2.iso

 

Both without success.

 

Should I use a syntax like pointing the hard disk to an image?

 

IE:

 

cdrom = [ ‘file:/root/installimages/winxpsp2.iso’]

 

(this does not work either)

 

When I issue the xm create winxp.hvm command I get the SDL window and see a quick screen with a “Q to quit” prompt (too quick to read it all) then see the bios screen pop up, get a could not read from boot device error in that screen and it dies.

 

 

If anymore information is required please let me know.

 

The platform is an AM2 4600+ chip riding on an MSI K9N SLI Platinum with a gig of Corsair Dual channel DDR2 with a WD SATA 160 gig drive. Running CentOS 4.3 64bit.

 

Also is it best practice to give guest OS’s individual partitions or use image files for their operating system? I could see portability being a huge plus with image files but maybe better performance from partitions. Has anyone had a chance to play with this using fiber channel SANs? Is it worth the effort?

 

 

Thanks,

Eli
