I just tried to switch from IDE -> SATA, using:
#!/bin/sh
VBoxManage storagectl $1 --name 'IDE Controller' --remove
VBoxManage storagectl $1 --name "SATA Controller" --add sata
VBoxManage storageattach $1 --storagectl "SATA Controller" --device 0 --port 0
--type hdd --medium /vm/${1}/hdd0.vdi
VBoxHeadless -startvm $1 &
The first one I did it on, I notice an ~20MB/s improvement in write operations,
based on running 'iozone 1024' … tried it on a test VM I created for this
purposes, so nothing else was running in it … but no problems …
So, moved over to a more production (not mission critical) box, everything
rebooted fine, then ran 'svnup' in order to download latest -STABLE code, and
build a new kernel … after several minutes, my Guest console (ala vnc) started
to spew CAM: Command timeout errors:
Tried to do a 'VBoxManage controlvm <name> poweroff', and it haves trying to
power down also:
# VBoxManage controlvm monitor.openstudent.ca poweroff
0%...10%...20%…
===
kill'd the process from the command line, restarted and it appeared to come up
fine …
has anyone seen something like this with SATA? I've never seen anything like
this with IDE …
