Instances lose internet

2020-04-06 Thread Adam Witwicki
Hello,

I wonder if anyone else has seen this, problerly not cloudstack but a user on 
our systems says that their instances randomly lose connection to the internet.
The windows instance says the nic is connected but can not ping any other 
server. There is no Virtual router as it's a L2 network
I found a post that mentioned an issue with bonding - but I can not see any 
bonding errors in the syslog

Thanks

Adam

...try:


On your management server, make sure the port TCP 8250 is open and 
reachable ( firewall open too )


ssh on your ssvm and run : usr/local/cloud/systemvm/ssvm-check.sh

any errors there ?

howto : 
https://cwiki.apache.org/confluence/display/CLOUDSTACK/SSVM%2C+templates%2C+Secondary+storage+troubleshooting


then, ssh on cvm and check the logs there ( /var/log/cloud.log ) any 
errors there ?

But if I ping the Private Ip it works:

I would like to know where I am sinning in these settings, as I cannot access 
the console view

If anyone could help me and thank you very much.
