Hi all,

We ran into a strange problem today. One domain has been created twice. See "xm list" :

Name Id Mem(MB) CPU State Time(s) Console

Domain-0 0 251 0 r---- 641.0

Domain-30 30 32 3 --p-- 0.0

oe45 30 31 3 -b--- 1.5 xx30

And xend.log :

[2005年08月22日 00:58:25 xend] DEBUG (XendDomainInfo:720) init_domain> Created domain=30 name=oe45 memory=32

[2005年08月22日 00:58:25 xend] INFO (console:94) Created console id=31 domain=30 port=xx30

Domain-30 has been automagically created while oe45 was starting !! Side effect is double :

- console for oe45 is unaccessible,

- destroying Domain-30 has destroyed oe45 also.

Xen is 2.0.6, Domain0 is 2.6.11.12 Debian Sarge. Xen tools are debian unstable .debs

Does anyone know the reason ?

We are unable to reproduce : it appeared at a time we were running some light stress tests (5-10 domu were starting/stopping).

Regards,

Sylvain COUTANT
