Q: Difference in xm and xl list I'm new to xen toolstacks - trying xe, xl.
Now i've created a guest os:
sudo virt-install -r 512 -n centos -f /dev/sdb --nographics --location http://mirror.centos.org/centos/6/os/x86_64

And want to see it in a list of DomU guests. Using xm:
[egor@xen ~]$ sudo xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  1024     1     r-----    160.8
centos                                           512     1                 0.0

But using xl:
[egor@xen ~]$ sudo xl list
Name                                        ID   Mem VCPUs  State   Time(s)
Domain-0                                     0  1024     1     r-----     164.8

Could you help me - why there is no centos in xl list?

A: libvirt doesn't support latest xen tool stack.
xm is old tool stack. xl is new tool stack.
maybe virt-instool used old tool stack. so xl can not recognize domU.
