[Xen-users] Error: (4, 'Out of memory', "xc_dom_boot_mem_init: can't allocate low memory for domain\n")

[Jose Rodriguez <joheiker@xxxxxxxxx>]

Hello everyone...

I get the following error when i try to creat a virtual machine

Error: (4, 'Out of memory', "xc_dom_boot_mem_init: can't allocate low memory for domain\n")

I'm using Xen under Gentoo, kernel 2.6.32-r1 in a i686 Dual Core AMD Opteron(tm) Processor 290 AuthenticAMD with 16Gb of memory and 4Tb of hard disk.

It was a pain to install xen in it but when i finally did it, i get this error whenever i try to create a vm.

I checked /var/log/xen/.log and here is some of the stuff i get:

domain-builder-ng.log

    virt_entry       = 0xffffffff80200000
    p2m_base         = 0xffffffffffffffff

    raise VmError(str(exn))
VmError: (4, 'Out of memory', "xc_dom_boot_mem_init: can't allocate low memory for domain\n")

I tried changing the memory of dom0 so i have more left for the domU's but it didn't work.

I don't know what else to do here. I've searched online, and nothing so far. I will go on w/ my search but if anyone has an idea or sugestion it will be useful.
