FREEBSD x64 or i386. ZFS pool. Guest OS Halt

[ALex]

Two weeks of busy with setting up a guest freebsd 8.1. When I use the ZFS pool system hangs at random moments tightly. If virtualboks runs under windows 7 then the problem occurs much less frequently. Tried different options for using or vmdk vdi disks. Under intensive operations to copy the guest OS, it hangs [halted]

I'd like to use virtualization is a zfs pool. What information is needed from me to attempt to resolve the problem?

I see similar problems with jumps in memory SOLARIS

ZFS VirtualBox Guest Settings

This is a 3 year old ticket, I know. I, too, am trying to virtualize ZFS.

Running under Windows 7, the two times my VM halted/paused was when the raw vmdk that was used was OFFLINE, or when there was a drive letter assigned to the volume.

According to ​http://www.virtualbox.org/manual/ch12.html#ts_config-periodic-flush

12.2.1. Guest shows IDE/SATA errors for file-based images on slow host file system

The symptom for this problem is that the guest can no longer access its files during large write or copying operations, usually leading to an immediate hang of the guest.

This sounded related to your case

Please reopen if still relevant with a recent VirtualBox release.
