why does my virtual machine freezes when I flush iptable
why does my virtual machine freezes when I flush iptable rules. i tried to install virtual machines 3 times and every time I flush iptables on host, virt machine freezes down. What can be the issue? Is it with the host installation or something else?

More info please. What virtualization? What kind of freezing? Why are you flushing iptables at all? It's configured for a reason....

i am using fedora13, and I have created a virtual machine vm01 on it. Purpose of vm01 is to check the mail configuration, using postfix and sendmail commands. I have installed mailx using yum. the moment "iptales -F" command is used on host machine, vm01 freezes, my mouse stop working on vm01 and I cannot type anything there. I have to restart the entire system. I tried to remove that vm and installed a new virtual machine vm03, but the freezing problem is persistent. I want to check If mail form host to vm and from vm to host can be send properly using " mail -s "PART E" root@[192.168.122.1] ".

Sorry but you've provided absolutely no useful information there at all. Please answer the questions I've already asked.

Also, keep in mind that if your policies are set to DROP, all affected packets will be filtered when you flush the chains (since there won't be any rules to send them to ACCEPT). So perhaps you should set your policies to ACCEPT before you flush? That is, assuming they're set to DROP (please confirm). Like acid_kewpie, though, I wonder why you're flushing in the first place. Please do try to provide us with more information. I mean, for example, we still don't even know what virtualization you're using.

Virtual machines have special ways to fake a nic. The flush is affecting those so until your real nics finish then virtual ones won't be ready.
