Ticket #5224 (closed defect: fixed)
VirtualBox stuck when multiple VMs run large NFS3 writes (Sun VDI 3.1)
|Reported by:||stegbk||Owned by:|
We are using a Sun VirtualBox VDI version 3.1 solution. For testing, we create VMs using 64-bit Ubuntu 8.04 desktop and have iozone run automatically on start up from the VDI administrator interface. The iozone benchmark writes/reads from an NFS3 mounted directory, which is served from a Sun Store x7310. One VM works fine, but when I get past 3-4 about 60% end up in a "stuck" state (I have generally tested with 10 and consistently end up with 6 stuck VMs).
This ends up being a fairly major problem because a user who is assigned to a stuck VM can do nothing to get a new VM from the pool without intervention by the VDI administrator.
