Thank you Pasi,
Here is what my grub.conf entry looks like (with the xen-3.4.1 tools
compiled,) after you install all 4 rpms from myoung's fedorapeople page: (
http://fedorapeople.org/~myoung/dom0/<http://fedorapeople.org/%7Emyoun...
)
title Fedora (2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE)
root (hd0,0)
kernel /vmlinuz-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE ro
root=/dev/mapper/vg01-lv_root rhgb quiet nomodeset
initrd /initrd-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE.img
When you compile and install xen-3.4.1 the following is created in /boot:
-rw-r--r--. 1 root root 498660 2009-07-07 17:08 xen-3.4.1-rc6.gz
lrwxrwxrwx. 1 root root 16 2009-07-07 17:08 xen-3.4.gz ->
xen-3.4.1-rc6.gz
lrwxrwxrwx. 1 root root 16 2009-07-07 17:08 xen-3.gz ->
xen-3.4.1-rc6.gz
lrwxrwxrwx. 1 root root 16 2009-07-07 17:08 xen.gz -> xen-3.4.1-rc6.gz
I modified it per the pvops wiki page: (
http://wiki.xensource.com/xenwiki/XenParavirtOps)
title Fedora (2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE)
root (hd0,0)
kernel /xen-3.4.1-rc6.gz dom0_mem=512M
module /vmlinuz-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE ro
root=/dev/mapper/vg01-lv_root rhgb quiet
module /initrd-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE.img
This looks correct..
This is what is in my /etc/fstab:
none /proc/xen xenfs defaults 0 0
So now I boot. When I boot the system the dom0 starts up instantly...., to
the point where it says "scrubbing free ram" then the screen goes blank and
all system activity ceases.
Hmm.. try removing the "rhgb quiet" from the vmlinuz line in grub.conf.
Is the last line you see something like this?:
(XEN) Scrubbing Free RAM: ..........done.
You could also try adding "loglvl=all guest_loglvl=all noreboot" to the xen.gz
line
to grub.conf.
So try with this grub.conf:
title Fedora (2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE)
root (hd0,0)
kernel /xen-3.4.1-rc6.gz dom0_mem=512M loglvl=all guest_loglvl=all noreboot
module /vmlinuz-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE ro
root=/dev/mapper/vg01-lv_root
module /initrd-2.6.31-0.1.2.37.rc1.git5.xendom0.fc12.i686.PAE.img
Has anyone tried these rpms? I am not sure if i can scream out
"bug!" "bug!"
because I cannot find anyone that has actually installed these rpms as part
of a deployment process, (a workflow, a howto, a "step by step" edit
"this"
or edit "that".) so I am not sure if it is that I am missing a config
parameter or not.
I've used self-compiled pv_ops dom0 successfully on my testing box, but I
haven't really tried this RPMs..
If you don't
My hardware:
Lenovo thinkpad T60 (Centrino Duo processor)
ATI Radeon X1300 card
(Its an "oldie" but on RHEL 5.3 it runs xen very very well.)
Laptop might be a tricky one.. but if RHEL 5.3 works on it, there's hope :)
