Hi Dave, thanks for uploading that. I have upgraded the DHCP server system to Quantal:
# dpkg -l | grep dhcp ii isc-dhcp-client 4.2.4-1ubuntu10.1 amd64 ISC DHCP client ii isc-dhcp-common 4.2.4-1ubuntu10.1 amd64 common files used by all the isc-dhcp* packages ii isc-dhcp-server 4.2.4-1ubuntu10.1 amd64 ISC DHCP server for automatic IP address assignment I switched the NIC type to virtio and confirmed the problem still exists. I then installed the updated packages from quantal-proposed: # aptitude install isc-dhcp-server/quantal-proposed isc-dhcp-client /quantal-proposed isc-dhcp-common/quantal-proposed Confirming new versions: # dpkg -l | grep dhcp ii isc-dhcp-client 4.2.4-1ubuntu10.2 amd64 ISC DHCP client ii isc-dhcp-common 4.2.4-1ubuntu10.2 amd64 common files used by all the isc-dhcp* packages ii isc-dhcp-server 4.2.4-1ubuntu10.2 amd64 ISC DHCP server for automatic IP address assignment The DHCP server log warnings do not appear any longer and DHCP is working as usual. So, it looks fixed to me. Thanks!
