AFAIK virtualized I/O is slowest part of virtualized world and building with bitbake is IMHO mostly about I/O. I'm running my gentoo system upgrades as well as all bitbake builds (workdirs) on raid0 - strip over 3 SATA2 disks (before that I was using huge tmpfs in RAM for workdirs - but that's not usable ie for OO.org build :)) And with chroot I can use it without any problem (just updated path in already used mount --bind). Also for running it from VM I would need to update host kernel from time to time, on the other side sharing kernel with my running system didn't create any OE related issue (except that sanity check for mmap with 2.6.33+ - which is already fixed) Regards, -- uin:136542059 jid:[email protected] Jansa Martin sip:[email protected] JaMa _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
