[libvirt-users] RH6 qemu expects driver name
Hi, I am trying to start machine on RH6. virsh # start ulp-001 error: Failed to start domain ulp-001 error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/1 qemu-kvm: -device lsi,id=scsi0,bus=pci.0,addr=0x5: Parameter 'driver' expects a driver name Try with argument '?' for a list. virsh # version Compiled against library: libvir 0.8.1 Using library: libvir 0.8.1 Using API: QEMU 0.8.1 Running hypervisor: QEMU 0.12.1 This is part of the config <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/rhev-data/defaultStore/ulp-001a.img'/> <target dev='sda' bus='scsi'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='scsi' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> Any tips? -- stereoIT - Open Source Technology Partners http://www.stereoit.com mobile: +420 776 762378

This is a really terrible QEMU error message. What it actually means is that LSI SCSI is not supported in this QEMU binary. Only IDE or VirtIO are supported block drivers in RHEL. No SCSI and no USB Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

Regards, Daniel Hi, this is bad, we want to migrate some machines from VMWare, but internal scripts relly on /dev/sda to be present. Is the support for 'scsi' planned for RHEL6?
Thanks for decoding the message for me ;) Regards, Robert

I expect it is fairly unlikely in the short term, since the QEMU code has some significant problems in the SCSI area wrt both performance and data integrity. VirtIO Block is going to be faster& more reliable, and IDE is going to be more reliable too (not sure of speed of IDE vs SCSI) Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
