are you seeing any messages on the host about the network bouncing?

The loss of connection is happening during the windows when the interface enters/leaves promiscuious mode. ----------------------------------------

CC: Subject: Guest VM dropping connection.

I am running RHEL5 Guest and Host. The guest OS is dropping network connections occasionally(I noticed my ssh session suddenly terminated). The guest is configured with private network interface and a public network interface. Following are the bridge/network settings for the host:

bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff              no                 vif2.0
vif1.0 peth0 vif0.0

xenbr1          8000.fefffffffffe             no                 vif2.1
peth1 vif0.3

xenbr1 is dedicated to provide the private network link for the guest os. Following is the guest OS configuration:

# Automatically generated xen config file
name = "saleen_webvm0"
memory = "1000"
disk = [ 'tap:aio:/vms/img/redhat/linux/es/5.0/x86_64/saleen_webvm0.img,xvda,w','phy:/dev/sdc,xvdb,w' ] vif = [ 'mac=00:16:3e:2e:6f:e1, bridge=xenbr0','mac=00:16:3e:2f:9e:b1, bridge=xenbr1',]
# vif = [ 'mac=00:16:3e:2e:6f:e1, bridge=xenbr0',]
vfb = ["type=vnc,vncunused=1"]
uuid = "122374dc-26a3-cb0d-99f8-3393e2481777"
bootloader="/usr/bin/pygrub"
vcpus=2
on_reboot   = 'restart'
on_crash    = 'restart'

Following is the output of ifconfig:
