Default configuration allows all VMs to access other VMs but not the network that the host machine is on. You can check the private network created by default: | |||
<source lang="bash"> | |||
# virsh net-dumpxml default | |||
<network> | |||
<name>default</name> | |||
<uuid>51beab57-eb0c-40b9-bb5e-957f31c1b489</uuid> | |||
<forward mode='nat'> | |||
<nat> | |||
<port start='1024' end='65535'/> | |||
</nat> | |||
</forward> | |||
<bridge name='virbr0' stp='on' delay='0'/> | |||
<mac address='52:54:00:f0:c0:2d'/> | |||
<ip address='192.168.122.1' netmask='255.255.255.0'> | |||
<dhcp> | |||
<range start='192.168.122.2' end='192.168.122.254'/> | |||
