Hi,
I have problem connectivity problem in my virtual machines.I am unable to connect to XEN VMs from my network. But my domU is visible in my route in the network as an attached device with the correct mac address. But I am unable to connect to other computers from my domU and vise versa. Please help.
Output of ifconfig from dom0 is given below

My vm.cfg file looks like
bootloader = '/usr/bin/pygrub'
disk = ['file:/OVS/seed_pool/OracleDB/System.img,xvda,w',
'file:/OVS/seed_pool/OracleDB/oracle11g_x86_asm.img,xvdb,w']
memory = '2048'
name = 'OracleDB'
on_crash = 'restart'
on_reboot = 'restart'
vcpus = 2
vfb = ['type=vnc,vncunused=1,vnclisten=0.0.0.0']
vif = ['bridge=xenbr0,ip=192.168.100.33,type=netfront,mac=00:16:3E:6E:64:3C']
vif_other_config = []
xend-config.sxp has following two lines:
(network-script network-bridge)
(vif-script vif-bridge)
Please let me know if any other information is needed.
Thanks,

I have a Dell Power Edge Server with 1 network card. I have installed VMWare ESXi 5 on it. Created several Windows 2003 Servers Virtual Machines. Networking is working fine all these windows machines. On one of the virtual machines I have installed Oracel VM Server 2.2.2 (Dom0) and on top of it I am trying to install Oracle VM Template for Oracle 11g provided by Oracle. I am having connectivity issues on the Oracle 11gDB (DomU). I can ping and ssh from Dom0 to DomU and vice versa. But I cannot connect the Oracle DB machine from any other machine. I can connect the Oracle VM Server (Dom0) from other computers in my network.
Any clue what the issue is ?
Thanks,
Ruchin
