hi all: after create VM, all of them can not connect,because mii does not exist. when i launch mii-tool ,error occurs. SIOCGMIIPHY on 'eth0' failed: Operation not supported. it is a debug environment Cloudstack 2.X, xenserver version is 5.6 SP2 1.have you all encountered this question? 2.when creating VIF, what kinds of ethernet created accordingly to VIF. E1000 or other else? i have tried to insmod dirvers of several ethernets,but error remains. 3. after creating of VM, IP address is correct on UI,but inside VM , IP is not configurated correctly. i have to set IP,netmask,gw manually. thanks.
