My bad. `ulimit -l unlimited` doesn't worked for me, but changing the
limit via /etc/login.conf did. Now it works flawlessly. Thank you!
Is there any resource where these cases covered ("Cannot allocate
memory" and disabling IOMMU because of erratas)? Just want to know
bloody details.
And one more question, am I right that PV-guests are no more supported
in FreeBSD? We tried to run Debian guest in PV mode like described here:
http://wiki.xen.org/wiki/FreeBSD_Dom0#Creating_your_first_PV_guest
but guest's kernel panicking like that:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
Full log: http://dpaste.com/2GZTJMH
Or it's some bad zfs setup on dom0 system?
This is FreeBSD HVM attempt:
libxl: error: libxl_dm.c:1482:device_model_spawn_outcome: domain 5
device model: spawn failed (rc=-3)
libxl: error: libxl_create.c:1319:domcreate_devmodel_started: device
model did not start: -3
libxl: error: libxl_dm.c:1586:kill_device_model: Device Model already exited
