I want to run Xen on a ubuntu 8.04 desktop release on a laptop. I would like to boot to Dom0 runing my normal gnome desktop, and from there start guest DomU''s as needed. Is this possible? The laptop uses a 2GHZ Pentium M, and has 2GB of ram. /proc/cpuinfo says it has PAE, though I don''t know if thats really relevant with 2GB of ram. There are no serial ports. I tried the instructions "Installing Xen On An Ubuntu 8.04 (Hardy Heron) Server" at http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories I haven''t gotten as far as adding a guest, I''m stuck on the reboot with the Xen kernel. When I boot, Xen seems to be going OK, and tells me its giving up the VGA. A little time goes on and then the VGA screen clears, after which there is no response to the keyboard or anything more on the screen. The laptop does in fact answer pings, and in fact accepts ssh connections. However, the ssh connections just hang with no response. I get the same behavior if I substitute "console=vga" for "console=ttyx" on the grub kernel params. Again, the laptop has no serial port. Is what I want possible? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

However, the ssh connections just hang with no response.I don''t know about the lack of keyboard or screen activity, but in the case where icmp works and tcp handshake packets work but tcp data packets don''t, i''d fire up tcpdump on another box and see if your tcp data packets are going out with invalid checksums (eg checksum offloading isn''t working). I''ve seen this before just recently on another mailing list. Of course there are a bunch of other causes that would give you the same problems too.

The tcpdump shows 1 0.000000 192.168.10.2 -> 192.168.10.30 TCP 61336 > ssh [SYN] Seq=3942416159 Ack=0 Win=49640 Len=0 2 0.000207 192.168.10.30 -> 192.168.10.2 TCP ssh > 61336 [SYN, ACK] Seq=895959597 Ack=3942416160 Win=5840 Len=0 3 0.000271 192.168.10.2 -> 192.168.10.30 TCP 61336 > ssh [ACK] Seq=3942416160 Ack=895959598 Win=49640 Len=0 4 38.858578 192.168.10.2 -> 192.168.10.30 TCP 61336 > ssh [FIN, ACK] Seq=3942416160 Ack=895959598 Win=49640 Len=0 5 38.859051 192.168.10.30 -> 192.168.10.2 TCP ssh > 61336 [ACK] Seq=895959598 Ack=3942416161 Win=46 Len=0 Nothing but the tcp handshake followed by silence until I break the connection. A more verbose dump shows no checksum errors. Ken _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
