I don't know if this is the same thing, but I noticed that my guest
domain (vm1) seems to have died twice and resurrected, leaving zombies
behind.

x235:~ # xm list
Name              ID  Mem(MiB)  CPU  VCPUs  State   Time(s)
Domain-0           0       121    0      1  r-----   3333.5

Zombie-1-vm1       5         0    1      1  ----cd      0.3
vm1                6       126    1      1  -b----    745.7
vm2                7       126    1      1  -b----    866.3

I am also seeing this messages on 'xm dmesg':
