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' =85 tried it on a test VM I =
created for this purposes, so nothing else was running in it =85 but no =
problems =85
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 =85 after several minutes, my Guest =
console (ala vnc) started to spew CAM: Command timeout errors:
=20
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%=85
=3D=3D=3D
kill'd the process from the command line, restarted and it appeared to =
come up fine =85=20
has anyone seen something like this with SATA? I've never seen anything =
like this with IDE =85=20
