Dave, could it be that the relatively-recent <bootorder> feature of libvirt caused a change to the behavior of the old <boot> element? If I'm not mistaken, with boot=c, boot was attempted from disk according to their specification order. David N, which vdsm and libvirt versions are you using? Please try with libvirt-0.8.7 if you haven't. (In reply to comment #6) > David N, which vdsm and libvirt versions are you using? Please try with > libvirt-0.8.7 if you haven't. I used: vdsm-4.9-69.el6.x86_64 libvirt-0.9.1-1.el6.x86_64 Tested with libvirt-0.8.7-18.el6.x86_64- same behaviour. (In reply to comment #7) > > Tested with libvirt-0.8.7-18.el6.x86_64- same behaviour. This puts the problem squarely on vdsm's field. Dan, Jiri did a bunch of work in this area, so I've asked him to respond. Actually, the regression is caused by qemu-kvm so just downgrading libvirt doesn't make it work again. However, the regression in qemu-kvm was intentional and libvirt needs to be learned to work with that. More details can be found in bug 704144. In short, libvirt used to use boot=on to say which disk is bootable but that is not supported by rhel qemu anymore and libvirt needs to use bootindex for this. *** This bug has been marked as a duplicate of bug 704144 *** |
Description of problem: When vm's system disk interface = VirtIO and adding IDE data disk the vm tries to boot from the additional disk instead of the system VirtIO disk. vdsm send the domain-xml with the following BIOS bootloader parameters: <os> <type arch='x86_64' machine='rhel6.0.0'>hvm</type> <boot dev='hd'/> <smbios mode='sysinfo'/> </os> those are general boot elements while per-device boot elements can be used (tested with the following parameters which works): <disk type='block' device='disk'> <driver name='qemu' type='qcow2' cache='none' error_policy='stop' io='native'/> <source

Version-Release number of selected component (if applicable): vdsm-4.9-69.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.install os on VirtIO system disk 2.add IDE data disk Actual results:
