Also, in device.map you can specify absolute paths, and the cd* and hd* images don't have to be in the same directory. Yes, looks like grub-bhyve needs the cd0/hd0 pair in device.map, but you even may cheat it like this: (cd0) /fake (hd0) /data2/mkushnir/tmp/diskdev-ubuntu-13 provided that "diskdev-ubuntu-13" has an installed OS on it. >> >> ... there are the following problems with this model though when doing >> mass VM's: >> >> * You have to copy the CD repeatedly to the boot dir (this is likely why >> openstack does not support cd based installs) >> * It makes for a really messy when attempting to make sure you completely >> nuke a vm when you delete it (currently pettiecloud does not delete the disk >> when the instance is deleted but this will be an option soon an likely the >> default) >> >> >> Of course the long term solution is unified off disk (vs. off loader) >> booting but until then any good work arounds? >> >> >> On Tue, Jan 28, 2014 at 6:23 AM, Markiyan Kushnir >> <markiyan.kushnir@gmail.com> wrote: >>> >>> 2014-01-28 Aryeh Friedman <aryeh.friedman@gmail.com>: >>> > Seems like it is a processor motherboard combo thing (see other thread) >>> > >>> >>> ah, ok. good to know :) >>> >>> -- >>> Markiyan. >>> >>> > >>> > On Sun, Jan 26, 2014 at 9:26 AM, Markiyan Kushnir >>> > <markiyan.kushnir@gmail.com> wrote: >>> >> >>> >> yes, once I posted it I realized that these sysctls are not relevant >>> >> at this stage. >>> >> >>> >> There was a segfault, was that bhyvectl?
