Re: convert .vmdk files
Hi Pete, 10. Add filters for popular VM file formats (VMDK, VHD, QCOW2) i have some .vmdk files for systems currently running VirtualBox i would like to port to bhyve. i also have a box running bhyve (10.1-rc2) that i can test patches and workflows as well. what is the work required for this entail? What you have to do today is to convert the VMDK to a flat file, e.g. using qemu-img. Ideally bhyve would be able to read/write VM file formats directly, perhaps with some sort of filter on top of the existing file backend code. There's plenty of GPL code around for this, but bhyve requires code with a BSD license. later, Peter. ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org
