[rlug] Problema cu XEN

2016-04-25 Fir de Conversatie Paul Lacatus (Personal) 
Am un serveras care ruleaza trei masini virtuale .  Sambata a cazut 
tensiunea mai mult de doua ore si alimentarea de rezerva a cazut. De 
atunci masinile virtuale pornesc dar nu au retea. Problema este ca ele 
se asteapta conform configurarilor la o interfata de bridge xenbr0 si 
mie mi se initializeaza xenbr1 dupa cum se vede mai jos
