I used to have USB flash with debian & KDE used for diagnostics and data recovery and used it in around 70 computers (at least according to generated unique ethernet interface names) without any problems. (we called it "promiscuous flash drive" :) It was variety of different desktops, servers , amd cpu, intel cpu ... never had a problem > > alexd > Libor

But it seems to be interesting, that some HW fingerprint is embeded in KDE config.

Re: Illegal instruction when running in kvm?
Hi, yeah, seems like that. I "fixed" it by deleting all KDE settings. I use this VM just for web browsing, so no big loss.

Re: Illegal instruction when running in kvm?
Hi, seems to be account related problem. No problem on fresh newly installed VM. No problem on fresh account on old VM. Maybe something with compositor? Thanks, Libor
