I am trying to run the amd64 9.2 bootable UFS disk image as a VM in vbox-4.3.12 on amd64 9.2 host system. It starts, but in a few minutes fails with an assert: 00:39:29.307864 !!Assertion Failed!! 00:39:29.307864 Expression: pCritSect->u32Magic == RTCRITSECT_MAGIC 00:39:29.307866 Location : /usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.12/src/VBox/Runtime/generic/critsect-generic.cpp(197) int rtCritSectEnter(RTCRITSECT*, const RTLOCKVALSRCPOS*) I am not sure if anybody ever tested virtual box this way, just reporting this issue here. My original purpose of doing this was testing out the upgrade to 10 process in a non-destructive way. But this apparently doesn't succeed so far. Bootable UFS is a snapshot of the live system: mount -u -o snapshot /huge-disk/snapshot.img / md0 is created with this command: mdconfig -a -t vnode -f /huge-disk/snapshot.img vmdk is created with this command: VBoxManage internalcommands createrawvmdk -filename vm-root.vmdk -rawdisk /dev/md0 --- vmdk disk file --- # Disk DescriptorFile version=1 CID=5c23f5d3 parentCID=ffffffff createType="fullDevice" # Extent description RW 356515855 FLAT "/dev/md0" 0 # The disk Data Base #DDB ddb.virtualHWVersion = "4" ddb.adapterType="ide" ddb.geometry.cylinders="16383" ddb.geometry.heads="16" ddb.geometry.sectors="63" ddb.uuid.image="c2680566-6c07-4268-b2a5-74588f4af8c9" ddb.uuid.parent="00000000-0000-0000-0000-000000000000" ddb.uuid.modification="714b9817-ca57-4c8d-8e87-c757bb14b78a" ddb.uuid.parentmodification="00000000-0000-0000-0000-000000000000" ddb.geometry.biosCylinders="1024" ddb.geometry.biosHeads="255" ddb.geometry.biosSectors="63" Yuri
