Hi, The netmask on my network is 255.255.0.0, yet the VMs get plumbed with 255.255.255.0. I have tried setting up the netmask using the onevnet command but I am not able to. Please help.
here are the network details of the main host - # ifconfig br0 br0 Link encap:Ethernet HWaddr 00:25:90:E2:C5:98 inet addr:172.16.192.60 Bcast:172.16.255.255 Mask:255.255.0.0 inet6 addr: fe80::225:90ff:fee2:c598/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10352600 errors:0 dropped:0 overruns:0 frame:0 TX packets:5714417 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6383539896 (5.9 GiB) TX bytes:8971371821 (8.3 GiB) # netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br0 172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br0 0.0.0.0 172.16.192.1 0.0.0.0 UG 0 0 0 br0 Here are the networking details of the VM: # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 02:00:AC:10:C0:40 inet addr:172.16.192.64 Bcast:172.16.192.255 Mask:255.255.255.0 inet6 addr: fe80::acff:fe10:c040/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:165669946 errors:0 dropped:1041 overruns:0 frame:0 TX packets:170954965 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:27122115947 (25.2 GiB) TX bytes:41114623111 (38.2 GiB) Interrupt:10 # netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.192.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 172.16.192.1 0.0.0.0 UG 0 0 0 eth0 Here is the onevnet definition - [oneadmin@fermi ~]$ onevnet show 0 VIRTUAL NETWORK 0 INFORMATION ID : 0 NAME : private USER : oneadmin GROUP : oneadmin CLUSTER : - TYPE : FIXED BRIDGE : br0 VLAN : No USED LEASES : 4 PERMISSIONS OWNER : um- GROUP : --- OTHER : --- VIRTUAL NETWORK TEMPLATE GATEWAY="172.16.192.1" NETMASK="255.255.0.0" USED LEASES LEASE=[ MAC="02:00:ac:10:c0:40", IP="172.16.192.64", IP6_LINK="fe80::400:acff:fe10:c040", USED="1", VID="20" ] LEASE=[ MAC="02:00:ac:10:c0:55", IP="172.16.192.85", IP6_LINK="fe80::400:acff:fe10:c055", USED="1", VID="13" ] LEASE=[ MAC="02:00:ac:10:c0:56", IP="172.16.192.86", IP6_LINK="fe80::400:acff:fe10:c056", USED="1", VID="9" ] LEASE=[ MAC="02:00:ac:10:c0:5c", IP="172.16.192.92", IP6_LINK="fe80::400:acff:fe10:c05c", USED="1", VID="19" ] FREE LEASES LEASE=[ MAC="02:00:ac:10:c0:57", IP="172.16.192.87", IP6_LINK="fe80::400:acff:fe10:c057", USED="0", VID="-1" ] LEASE=[ MAC="02:00:ac:10:c0:58", IP="172.16.192.88", IP6_LINK="fe80::400:acff:fe10:c058", USED="0", VID="-1" ] LEASE=[ MAC="02:00:ac:10:c0:59", IP="172.16.192.89", IP6_LINK="fe80::400:acff:fe10:c059", USED="0", VID="-1" ] LEASE=[ MAC="02:00:ac:10:c0:5a", IP="172.16.192.90", IP6_LINK="fe80::400:acff:fe10:c05a", USED="0", VID="-1" ] LEASE=[ MAC="02:00:ac:10:c0:5b", IP="172.16.192.91", IP6_LINK="fe80::400:acff:fe10:c05b", USED="0", VID="-1" ] LEASE=[ MAC="02:00:ac:10:c0:5d", IP="172.16.192.93", IP6_LINK="fe80::400:acff:fe10:c05d", USED="0", VID="-1" ] VIRTUAL MACHINES ID USER GROUP NAME STAT UCPU UMEM HOST TIME 9 oneadmin oneadmin testvm9 runn 0 512M test 32d 20h47 13 oneadmin oneadmin testvm1 runn 0 2G test 29d 02h33 19 oneadmin oneadmin testvm2 runn 0 2G test 3d 17h13 20 oneadmin oneadmin testvm3 runn 1 2G test 3d 15h54 [oneadmin@fermi ~]$ Regards.
