[Xen-devel] disk=['file://..xvda'] not working for boot disks anymore?
Hey, This parameter disk = ['file:/root/sol.dd,xvda,w','file:/root/sol-11_2_15_5_1-text-x86.iso,xvdb:cdrom,r'] works with qemu-traditional, but if I try with qemu-xen it does not find the disk: (d15) [2016-01-22 20:50:03] enter handle_19: (d15) [2016-01-22 20:50:03] NULL (d15) [2016-01-22 20:50:03] Booting from ROM...

And I dug in the thread. There is a bit of problem here. This patch breaks some existing guests (Solaris 11.2 for example). It assumes that when running under Xen it would only use PV drivers. Which is fine - except that the bootup part (GRUB2) is all done using QEMU - and if the guest config has 'xvda' then SeaBIOS won't see the disk anymore. QEMU traditional will still show the disk. Ideas how to deal with the existing guests? P.S. Solaris OS cannot run as PV guest, only HVM. ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

I'd prefer this not be reverted, and instead use 'hda' in your config. Unless you know of another way for libxl apps to request a xen virtual disk without the accompanying emulated one.
