Should we ask why they do that, and investigate whether that > can change (and, of course, whether that is enough for us) ? This still seems to be true - I guess I've been building my own for a long time or using virt-preview and just now had the opportunity to notice that the stock f20 qemu still fails with virt-install. # virt-install --name=testvm --ram=2048 --vcpus=2 --cpuset=2-11 --location=http://librescu/cobbler/ks_mirror/centos6-x86_64 --os-type=linux --os-variant=rhel6 --disk path=/dev/zvol/storage/testvm/boot --disk path=/dev/zvol/storage/testvm/root --network bridge=br0,mac=02:00:0a:0a:0a:19 --graphics=vnc --paravirt --arch=x86_64 --virt-type=xen yields: # tail -100 /var/log/libvirt/libxl/testvm.log | grep libxl__spawn_local_dm | grep -v Spawning | cut -f 6 -d ' '| xargs echo /usr/bin/qemu-system-i386 -xen-domid 13 -chardev socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-13,server,nowait -mon chardev=libxl-cmd,mode=control -nodefaults -xen-attach -name testvm -vnc 127.0.0.1:0 -k en-us -machine xenpv -m 2049 which gives: Option xen-domid not supported for this target etc. I see the f21 version (I built the matching version from virt-preview on f20) works fine and I've been using the above pattern for a couple years on f[1?-20]. Is it time to just enable xen for f20 since it works and f20 will be supported for a while yet? It was a little tricky (aka time-consuming) for me to track this down and I have a slight clue how the parts work - failing for historical reasons seems to be incorrect and will unnecessarily confuse a large part of the user base. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.855.SW.LIBRE Email, IM, VOIP: bill@xxxxxxxxxxxxxxxx VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle
