[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?

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'' ] Best Regards, Yongkang (Kangkang) 永康 ________________________________ From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Eli Robinson Sent: 2006年9月12日 3:30 To: xen-users@lists.xensource.com Subject: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006 I grabbed the unstable download from 9-7-2006.

RE: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006
Yes that solved the issue! I am now fighting a no keyboard on xp installer issue, I can not specify the HAL to use as I have no keyboard in either VNC or SDL so I can not hit F5 or F7. I am doing a yum update on the OS now to see if it may correct the problem.

(this would be for Xen 3.0+, presumably...?) I''ve always thought it a weakness of Xen that you could not install a DomU from CD-ROM (or ISO image, as above). My machine I am using at home is not a VT-enabled one, so being able to install a guest domain from an ISO would save a few steps in my current process (install to my desktop in VMware --> loopback-mount the disk image on Dom0 --> rsync the filesystem created in VMware to the mounted disk image) Thanks. -Alan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] cd-rom access, hvm boot, unstable download from 9-7-2006
maybe Im reading too much into your post, but you install XP in VMWare and then copy it into a xen VM and run it without a VT enabled CPU?
