Hello,
I have a small fail with my first Xen install. Il have before reading
docs and FAQs and send quenstion on xen-fr list without success. So i
try to translate my mail in english to post in xen-users mailing list,
excuse me for my bad english.
I have hoped to find an easy way in using Xen packages from Mandriva
2007.0 (for x86_64) where i found xen binaries and compiled xen
kernels.
With a doc about Xen in mandriva 2006.0 from xenfr.org web and some
other stuff take on web, i succes starting 2.6.17-5mdvxen0 kernel on
my computer. I also start xend and xendomains.
I construct a virtual host disk in a file, inclding ext3 fs,
copy/update of files of my runing OS (based on docs items).
I start a config for my virtual host from xmexample1, using
"file:/...", and no network for begin. You can see this config
in first line of logs at the end of this mail.
After many tries of virtual hostname create, i always get the same
2 lines :
# xm create x1
Using config file "/etc/xen/x1".
Started domain ExampleDomain
#
And I get back the prompt. On web i see surch trace where my two
lines are usualy folowed by many lines of boot.
I have try somes changes : '-c', with network, and with folowing
ramdisk config. I get always only the same two lines.
xm create /dev/null ramdisk=/boot/initrd.img \
kernel=/boot/vmlinuz-2.6.17-5mdvxenU \
name=ramdisk nics=0 vcpus=1 \
memory=64 root=/dev/ram0
In xend.log i just see my virtual host noticed 'crashed' but without
begining to boot. I attache surch log (i use xen debug package) at the end
of this mail.
Si if somebody who have more knowledges than me about XEN (very easy
because i am a small beginer) can see my logs and show me a way to
succes run a virtual host, i will be very happy. I can send all data
you were agree to see, and make all tries. I cas also resume answers
for next users.
thank's you for all,
Roland Touchais
