I have a machine running 4 VMs on it. There is one Fedora VM which is causing me some trouble. The IPs of the VMs are something like 10.100.100.* I have a Windows PC which is in the same network. It has an IP 10.100.25.77. When I reboot the Fedora VM, I am able to ping it from my Windows PC as well as use putty to ssh to it. The next day, I cant ping it or ssh from my Windows PC. However I can ping and ssh to the other VMs on the machine. If I ssh to one of the other VMs, I can ping and ssh to the Fedora VM. Next if I restart it, things get back to normal and I can access it without any issues. The IP of the VM doesn't change after rebooting and it is statically assigned

I would like to know what is causing this and how to get it fixed.

As a last resort, I am thinking of running a cron job to restart the VM every night, it is not a critical server, but will be generally used occasionally in the day time.
