I have installed xen 3.0.4 from
http://xenbits.xensource.com/xen-3.0.4-testing.hg. Now when i want to setup
winxp as a domu on this server. The server is a Intel Core 2 Duo with 4GB
RAM.

I took the xmexample.hvm as an example for the config. Here is the edited
version.

Now when i run "xm create xm1", it gives me the following error:

Using config file "./xm1".
Error: Kernel image does not exist: /usr/lib/xen/boot/hvmloader

I checked in the /usr/lib/xen/boot directory and it seems to be empty. Can
anyone please tell me how to get this hvmloader ??

Thanks.

In 3.0.3, if it failed to compile some of the hvm tools the build would
still continue. You may simply just be missing bcc or cpp respectively. 

I find its handy to redirect make output (nohup or tree is handy for
this) to a file so I can review it later to see if something went wrong.

I'm not 100% sure that in 3.0.4 the build process won't halt if it can't
build some of the qemu / hvm related tools. More than likely you were
missing stuff make needed to build it, but it didn't halt .. and just
flew by.

Best,

Thanks for the quick response Tim.

Inside xen 3.0.4, tools directory, i ran "make all; make install" and i got
hvmloader now inside /usr/lib/xen/boot. However when i try to start the
domU, it just hangs.

Here is the log extract from xend.log

Dear Ryan,

Here is the latest log file content. If i missed in my earlier post, the
file system which i was passing in the config is basically a raw lvm which i
planned to use for the installation. The system was suppose to boot up from
the cdrom.

domid: 8
qemu: the number of cpus is 1
qemu_map_cache_init nr_buckets = 200
shared page at pfn:1ffff
buffered io page at pfn:1fffd
xs_read(): vncpasswd get error.
/vm/c4e43b63-a488-90eb-1f7a-ed8c168b90a9/vncpasswd.
char device redirected to /dev/pts/1
I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0

It's still just a warning, so you have to keep an eye out for it.

Possibly we should make bcc a build requirement now, as I'm sure most people
building Xen want the HVM functionality.
