I too I'm experiencing some packet loss: this is particularly visible for UDP traffic. Around 4% of bytes transferred get lost (in UDP). I've a thread on xen-users ML, if you have comments. Experimenting with VMware ESX V3 give me -- for udp traffic -- a 0.8% loss for bytes transferred. XenSource will release XenEnterprise 3.2 (still in beta) at the end of March. They will provide Vlan management, but still don't know if this problem will be present. As for the other solution you suggest (Vlan's inside the guest) I think it's less secure and so less acceptable. Regards, -- Marco Hi Felipe,

EL problema es que yo quiero que esas maquinas virtuales no se vean entre si es decir desde afuera.. por eso pensaba en hacer un bridge para cada maquina virtual o crear un vlan y hacer lo mismo con los bridge.. no se que me recomiendas tu y se me podrias guiar un poco gracias ___________ __________ > |VM1 |----------------bridge1-------------------| | > |________| > | | > ____________ > | |-----BALBLA > |VM2 | > | VM4 | > |__________ |-----------------bridge2----------------|Firewall | > ____________ | > | > |VM3 | > | | > |__________ |-----------------bridge3------------------ |________| Jeje, bueno estoy virtualizando con xen un servidor. cual tiene dns, imap,postfix bla bla, en cuatro maquinas virtuales.
