Hello guys,

i've just installed kernel 3.4 from Ubuntu kernel PPA archive and after this upgrade VM aren't able to get the DHCP address but with tcpdump i see the request and offer on the network.
Someone else experienced this? I've tried also with 3.3, same story. Rolling back to 3.2 and everything works fine.

I've tried with both flatdhcp and vlan mode.

Best

Alessandro

Also, when testing FlatDHCPManager are you using multi_host mode, or isDHCP being served from a central nova-network node? What ethernetdriver are you using?


Thanks,
