How is it in direct comparison with Qemu?
Just installed the Etch .deb (went well, even kernel module compilation; though it didn't get the permissions of /dev/vboxdrv quite right). The GUI is really good; it was easy to configure a new VM. For testing, I started Ubuntu Edgy Desktop CD in VB and Qemu (0.8.2, taken from CVS in Nov. 2006), both without hard disk, with audio, with 192 MB, with normal kqemu (no kernel emulation). Both systems start in reasonable time (didn't measure it, though). It seems like the VB graphics emulation is snappier: in Qemu, it always feels (and always felt) somewhat laggy and slow, while in VB it felt faster. Note: I tried Qemu with and without -std-vga; in VB I didn't install any guest stuff. In general, graphics in VB seem faster; while in Qemu I could notice how the menus were displayed (first the frame, then the interior), in VB the menus were "immediately" there. I think that's a very important thing, because currently Qemu _feels_ slow on the desktop, even though it's CPU performance is probably as fast as VBs or VMWares! Hopefully the VB devs will give some of their improvements back to Qemu (apparently their graphics emulation is based on Qemu's). Afterthought: using Qemu with -kernel-kqemu makes the menu drawing as fast as with VB, but mouse still feels laggy. What else: VB sound was choppy when playing a video, while in Qemu the same video was with good sound, bad choppy display. It seems like VB doesn't use something like -kernel-kqemu; during Ubuntu boot, host CPU was only used by userland apps, while with Qemu with - -kernel-kqemu 80% of host CPU was used by kernel. VB offers some guest tools (didn't try them), but without guest tools there is smooth mouse-transition (Qemu does this nicely with tablet emulation). All in all I like VB for its easy GUI and good responsiveness; hopefully this can be combined with Qemus broad host arch support :-) Regards, Oliver _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFFrABTTFOM6DcNJ6cRAs9hAKDkcCWl+QLgvKHExT7fP4sBzWFIhgCgu3Jf U4GFShn4GnpKGBoxMa5LNpg= =pfoh -----END PGP SIGNATURE----- _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
