[xenpreview-dev] initial vm creation reports "not enough free memory" and xm info returns error "int exceeds XML-RPC limits"

[Krysan, Susan]

We are using SLES10 Xen with the recommended xen security update on
Unisys ES7000/one host with 8 processors and 32GB RAM.  Immediately
after successful installation, we updated menu.lst to make xen the
default boot option and added kernel parameter to boot xen with
dom0_mem=512M.  When we attempt to create our first VM using yast, the
hardware section of the virtual machine settings indicates in red
letters: "Not enough free memory (0 MB available)."  The default memory
setting for the vm is 256MB.  Xm top shows 31.5GB free memory.  Also, xm
info returns Error: int exceeds XML-RPC limits.

 

We rebooted with dom0_mem=1024M and did not get the error message.  We
then rebooted with dom0_mem=512M and were able to successfully use xm
create (instead of using yast vm interface to create) to create a
virtual machine with 256mb memory.  Since then, we are no longer able to
recreate the original not enough free memory error.  

 

Any ideas why we get the not enough free memory and xm info errors?

 

Thanks,
