[Xen-users] Domain created twice ?

["Sylvain COUTANT" <sco@xxxxxxxxxx>]

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 :

 

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

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,
