Yes virt-manager works fine.

I connected via virt-manager to qemu:///session as unprivileged user and
created several machines, started them and then connected via virsh,
rechecked the machines and stop them. Everything works fine. No error
messages on the console. True for both numa-capable and not numa-aware
hardare.

Using the libraries on a machine without numa support does not create
any warnings when using the appropriate commands:

# LANG=C virsh nodeinfo
CPU model:           x86_64
CPU(s):              4
CPU frequency:       2327 MHz
CPU socket(s):       1
Core(s) per socket:  4
Thread(s) per core:  1
NUMA cell(s):        1
Memory size:         32946132 kB

# LANG=C virsh freecell
Total: 25699544 kB

# LANG=C virsh freecell 1
error: internal error start cell 1 out of range (0-0)

The last error message is expected since there is no numa cell 1

Thanks a lot,

Ralf
