Error creating domain - int argument required

Error creating domain - int argument required

[Ignatia Suwarna]

[-- Attachment #1.1: Type: text/plain, Size: 494 bytes --]

I got this error message when trying to create a domain, from the Fedora Xen 
quick start docs. 
 "Error: Error creating domain: int argument required"
 I found relevant information from the archive, but I can't clearly point 
out what the solution was:
http://lists.xensource.com/archives/html/xen-devel/2004-08/msg00282.html
 It seems like the problem is due to the fact that my system doesn't have 
/dev/sda1. How do you get away with this?
 Any helps would be greatly appreciated.

Here is my domU config:
kernel="/boot/vmlinuz-2.6.12-1.1447_FC4xenU"
memory=64
name="rawhide"
nics=1
disk=['file:/root/fedora.img, sda1, w']
root="/dev/sda1"
extra="rp selinux=0 3"
 I also started over with hda1, since there is /dev/hda1, but it gave the
same error:
Error creating domain, int required.
 Is this a known issue? Or something wrong with my config??

I think it is a bug. I am seeing this problem, too, using the latest hg
pull, changeset 6987. I have opened up a bugzilla report on it, #246.

Do you have anything useful in /var/log/xend-debug.log?  Type errors like this
usually appear there.

I'm seeing this now as well. It may be a new regression. Next time a
changeset is hit where this config works without any issues let me know -
I'm not having much luck.

I found the problem. Your changes to the parsing code earlier today made it
less tolerant of unset values where you're expecting a type. Adding cpu=-1
to the command line made the complaints go away.

On line 221 in XendDomainInfo.py you may want to change
result['cpu'] = get_cfg('cpu', int)
to
result['cpu'] = get_cfg('cpu')
and then change the current behaviour for -1 to handle None.

Removing the spaces seems to work. Thankss a lot.
 I was wondering where can we get other packages for domainU? I'd like to
try different guest OS-es. The host is running on Fedora Core 4.

I removed the spaces, as suggested by Ted, but no difference.

Try removing the spaces between the brackets on your disk line.
Other than that everything flies with the configs  I have.
