5:53 a.m.
I have performed a basic FC5 install for the purpose of texting Xen. The
machine is a Compaq Evo P4-1.5GHz with 384M of RAM.
http://jailtime.org/download:centos:v4.3
I downloaded a CentOS 4.3 Xen image from the above URL for the purpose of
testing, the CentOS image in question was designed for 128M of RAM so should
run nicely on a machine with 384M.
kernel = "/boot/vmlinuz-2.6.15-1.2054_FC5xenU"
memory = 128
name = "centos.4-3"
dhcp = "dhcp"
disk = ['file:/xen/centos.4-3.img,sda1,w',
'file:/xen/centos.swap,sda2,w']
root = "/dev/sda1 ro"
Above is the contents of my /etc/xen/centos config file. Below are the errors
I get in my /var/log/xend-debug.log file. The command "xm create -c centos"
gives the error "Error creating domain: The privileged domain did not
balloon!".
Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/xen/xend/server/SrvDomainDir.py",
line 77, in op_create
dominfo = self.xd.domain_create(config)
File "/usr/lib/python2.4/site-packages/xen/xend/XendDomain.py", line 226, in

dominfo = XendDomainInfo.create(config)

vm.initDomain()

File "/usr/lib/python2.4/site-packages/xen/xend/balloon.py", line 120, in
free
raise VmError('The privileged domain did not balloon!')
VmError: The privileged domain did not balloon!
Any suggestions on what I should try? I repeated the same situation on an
identical machine (I have a set of identical Compaqs for testing) running FC5
with some packages upgraded to rawhide versions (but there seem to be no
usable Xen updates in rawhide).
I'm trying to fix the SE Linux policy bugs related to Xen but I can't even get
Xen working in permissive mode.
PS Please CC me on any replies as I have many unread messages in my lists
folder.

domain 0 grabbed all of memory and isn't letting it go. try adding
dom0_mem=128000
to the end of the kernel line in /etc/grub.conf (saying kernel /xen.gz
...) and rebooting. I'd suggest going to runlevel 3 to avoid starting up
X with so little memory.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Thanks for the suggestion. The dom0_mem parameter doesn't seem to do
anything, but this suggestion led me to "xm mem-set 0 128" which works!
I've now got the base Xen functionality working so I can fix the SE Linux
policy. I should have a new policy available in about 24 hours to make Xen
work properly.

I made a mistake before. I had the dom0_mem parameter on the module line for
the Linux kernel rather than the kernel line for Xen. Now it works as
desired.

I've never used the jailtime images, but I notice from the site
"Prerequisites : Working installation of Xen 2"
But FC5 includes xen 3
Jailtime just has images of Ext2/3 file systems with Linux installed. Since
solving the memory issue I booted up the CentOS image in question and logged
in to it. So it seems to be working OK.
Someone reported a SE Linux policy bug when running Jailtime images. I will
fix that bug shortly.
