[Fedora-xen] Problem Installing Fedora 7 as a Guest on Xen machine
Hi I have run into a problem installing fedora 7 as a guest on a Xen machine. The host machine is a amd64 - Debian lenny install. Running 2.6.20-1-xen-amd64 xm info host : debxen release : 2.6.20-1-xen-amd64 version : #1 SMP Tue Apr 24 22:23:22 UTC 2007 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 2800 hw_caps : 178bfbff:ebd3fbff:00000000:00000010:00002001:00000000:0000001f total_memory : 8191 free_memory : 1 xen_major : 3 xen_minor : 0 xen_extra : .3-1 xen_caps : xen-3.0-x86_64 hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : Tue Oct 17 22:09:52 2006 +0100 cc_compiler : gcc version 4.1.2 20061028 (prerelease) (Debian 4.1.1-19) cc_compile_by : ultrotter cc_compile_domain : debian.org cc_compile_date : Fri Nov 3 00:21:27 CET 2006 xend_config_format : 2 I have downloaded the fedora 7 DVD, I have extracted the xen vmlinuz and zen initrd.img This is my fedora7.cfg # # Kernel + memory size # kernel = ''/etc/xen/data/fedora7/vmlinuz'' ramdisk = ''/etc/xen/data/fedora7/initrd.img'' memory = ''1024'' extra = ''pnpacpi=off sync_console vnc vncpassword=qwerty text vncconnect=16.144.29.11'' #bootloader = ''/usr/lib/xen-3.0.3-1/bin/pygrub'' # # Disk device(s). # disk = [ ''phy:vglocal/fedora7-disk,xvda,w'' ] # # Hostname # name = ''fedora7'' # # Networking # dhcp = ''dhcp'' #vif = [ ''type=ioemu, bridge=xenbr0'' ] vif = [ '''' ] # # Behaviour # on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' serial = "pty" localtime = 0 vcpus = 2 I tried something similar with RHEL5 and it worked, fedora7 is getting stuck>From xm console fedora7io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered (default) pci_hotplug: PCI Hot Plug PCI Core version: 0.5 rtc: IRQ 8 is not free.

Can any one provide any hints or know what is going wrong. Maybe there is a mis match of the xen versions ??? Thanks Alex

Re: [Fedora-xen] Problem Installing Fedora 7 as a Guest on Xen machine
Hello,
You do not specify your exact problem with the installation.
Are you using the kernel and initrd from the images/xen/ directory of
the Fedora 7 installation tree? If so, most probably your guest is
running ok and the Anaconda loader has started and is waiting for
input on the guest''s local console.
The local console is differrent from the serial console accessed by
"xm console" and it is a new feature in Xen 3.1 and Fedora 7.
The guests now have a "real" monitor which can be accessed remotely
by VNC. This VNC server is not the Anaconda VNC server for network
installation of Fedora that you are trying to start with the "vnc",
"vncpassword", and "vncconnect" kernel options. It is
started by xend
on the Xen host.
Have a look at all vnc related configuration variables by issuing "xm
create --help_config".
Try to configure and connect to the guests''s monitor and see if
Anaconda is running and waiting for some user input.
Have in mind that there are problems related to VNC network
installations of Fedora 7:

Everything is totally non-responsive. Even the little comet orbiting the cursor in the console freezes up (along with the cursor). It acts exactly like this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=237895 except "random time" always happens before I can even get it through an install :-). The dom0 is running Xen in fedora core 6 (x86_64), I''m trying to install an i386 guest fedora 7 (fully virtual). I also have to use the noisapnp=1 kernel boot parameter to even get this far, otherwise it hangs when booting the kernel to do the install at the "scanning for isa pnp cards" step. And, in addition to that, the fedora 7 kernel apparently doesn''t have (or can''t find) a driver for the emulated cdrom, so I have to do a network install rather than installing completely from the DVD iso image. I can work around most of these, but the freezing during install is harder (though I''ve seen some folks using the livecd builder to build images for xen guests, which might be an approach, but I haven''t looked at trying to figure that out yet).
