Hi, I run 2 VM on 2 different hosts (VM XP run on host 1, VM hyperv run on host 2, and VR running on host 2, VR's ip address is 10.1.1.1. All host running on the same VLAN), only VM hyperv obtained IP address from VR. This is result in /var/log/message on VR:
Sep 8 04:12:13 r-468-VM cloud: edithosts: update 02:00:27:b0:00:35 10.1.1.90 XP to hosts Sep 8 04:12:13 r-468-VM cloud: /root/edithosts.sh: setting default router for 10.1.1.90 to 10.1.1.1 Sep 8 04:12:13 r-468-VM cloud: /root/edithosts.sh: setting dns server for 10.1.1.90 to 10.1.1.1 Sep 8 04:12:44 r-468-VM cloud: edithosts: update 02:00:04:d3:00:3a 10.1.1.107 hyperv to hosts Sep 8 04:12:44 r-468-VM cloud: /root/edithosts.sh: setting default router for 10.1.1.107 to 10.1.1.1 Sep 8 04:12:44 r-468-VM cloud: /root/edithosts.sh: setting dns server for 10.1.1.107 to 10.1.1.1 When I use renew ip address command on VM XP (run on host 1, other with VR) and tcpdump command on VR then I don't receive any DHCP packet from VM XP. Can u help me ?

If no - this issue sounds like something wrong with your VLAN configuration. If there are no VLANs configured on your switch check if all packets are broadcast all over or if they are getting ignored. > > > Can u help me to resolve this problem > > Ps: Can u send me detail document about cloudstack networking ?
