Re: Virtualbox vs VMware for Fedora?

How is the virtual networking in QEMU/KVM/libvirt? can I just click into settings and 'add' a network interface?

I have done it.

Converting OVA for use with KVM / QCOW2

The OVA file is nothing more than a TAR archive, containing the .OVF and .VMDK files. Easy!

Using Evergreen ILS for example:

~ $ file Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ova:                POSIX tar archive (GNU)

I'ts possible to use the tar command to list the contents

~ $ tar -tf Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ovf
Evergreen_trunk_Squeeze-disk1.vmdk

Simply extract those things...

~ $ tar -xvf Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ovf
Evergreen_trunk_Squeeze-disk1.vmdk

Now take a look at the created files The OVF XML file describes the image, it makes for some interesting reading about the expectations of the running environment.

~ $ file Evergreen_trunk_Squeeze*
Evergreen_trunk_Squeeze-disk1.vmdk: VMware4 disk image
Evergreen_trunk_Squeeze.ova:        POSIX tar archive (GNU)
Evergreen_trunk_Squeeze.ovf:        XML document text

Recent versions of qemu are able to run directly from the VMDK file, buy why do that? Use QCOW2, it's better. Execute: qemu-img -h and the last line of output shows the supported formats.

~ $ qemu-img -h |tail -n1
Supported formats: raw cow qcow vdi vmdk cloop dmg bochs vpc vvfat qcow2 parallels nbd blkdebug sheepdog host_cdrom host_floppy host_device file

Now actually convert it, this may take some time.

~ $ qemu-img convert -O qcow2 Evergreen_trunk_Squeeze-disk1.vmdk Evergreen_trunk_Squeeze.qcow2
