Subject Re: Cannot create VM Instances . S-1-vm cannt reach guest network gateway
Date Wed, 31 Oct 2012 10:01:51 GMT
Inside SSVM, check net.ipv4.conf.default.rp_filter setting in sysctl:
# grep "rp_filter" /etc/sysctl.conf     // except value: 0
# sysctl -A |grep "default.rp_filter"  //except value: 0

If runtime sysctl is not 0, you may use below command to disable it:
#sysctl -w net.ipv4.conf.default.rp_filter=0

Then try again, if issue persist still, try to destroy the SSVM and
test in new created one.
