I am new to virt-manager
.
After having configured a virtual network (new interface virbr0
) with 2 VMs that should be able to communicate, I discovered that most ports are filtered.
For example, the two nodes are mutually reachable via port 22, but for other ports, for example higher than 9000, I get a no route to host
.
trying to connect to the port 80, that is open on host 192.168.122.125, this is what I get with tcpdump:
07:50:55.363767 IP 192.168.122.14.54483 > 192.168.122.125.80: Flags [S], seq 21091821, win 14600, options [mss 1460,sackOK,TS val 313139 ecr 0,nop,wscale 7], length 0
07:50:55.364204 IP 192.168.122.125 > 192.168.122.14: ICMP host 192.168.122.125 unreachable - admin prohibited, length 68
Why is this? Is it possible to remove some filters, to allow at least the nodes to be able to communicate on various ports?
tcpdump
while you try to reach those ports and see what happens.
