I have never used "xl console" with a HVM, only vnc, but be aware that the vnc server is only listening on 127.0.0.1 on the DOM0 (the vnclisten seems to be ignored, for me anyway). So, you have to have vncviewer on the DOM0 itself and use X forwarding or use ssh and port forward something like 127.0.0.1:5900 (or whatever port you ended up with) from the DOM0 to an external address or other location. With the instance running, do a "netstat -an|grep 59" and see if there is anything running on 5900+ .. that will be the vnc address+port you want to hit. You *may* want to use "boot='d'" and specifiy that the iso is a CDROM. Something like this: 'file:/lhome/xen/isos/archlinux-2022.08.05-x86_64.iso,ioemu:hdc:cdrom,r' You will probably also want to add a hard drive as some of the installers get unhappy without one (if I remember it all correctly). Usually I put the hard drive on hda, and use hdc for the cdrom. You will be fine NOT using qemu traditional with a file backstore (my example had qemu traditional specified), but if you use LVM LVs, the upstream qemu doesn't deal correctly with them (I posted about this on port-xen a while ago). As for trying the Debian distro, I don't remember trying that one. Assuming that nothing is too strange about it, it will probably be fine. It *MAY* (and probably will) notice that it is running in a Xen world and try to be a PVHVM or even PVH guest after it starts which should not be a problem. > Thanks a lot. > > Cheers, > Brook -- Brad Spencer - b...@anduin.eldar.org - KC8VKS - http://anduin.eldar.org
