[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-0ÂÂÂÂÂÂÂÂÂÂ 0ÂÂÂÂÂ 251ÂÂÂ 0Â r----ÂÂÂ 641.0

Domain-30ÂÂÂÂÂÂÂÂ 30ÂÂÂÂÂÂ 32ÂÂÂ 3Â --p--ÂÂÂÂÂ 0.0

oe45ÂÂÂÂÂÂÂÂÂÂÂÂÂ 30ÂÂÂÂÂÂ 31ÂÂÂ 3Â -b---ÂÂÂÂÂ 1.5 ÂÂÂxx30

 

And xend.log :

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,
