Imagine the situation when there is some remote host machine with several VMs. You have an SSH access to host machine, but no VNC to manage easily those VMs, even doing the most elementary actions.<\/p>\n\n\n\n
Listing all your VMs:<\/p>\n\n\n\n
alexey@amd:~$ vboxmanage list vms\n\"centos7-orig\" {e4077fae-1be5-42f4-ae40-b399f98c6e3d}\n\"debian9.rtpengine\" {d2fb6655-29ab-4103-a70c-b7234c835a79}\n\"debian9.opensips1\" {757f6235-27d4-470d-a461-c12fbfe0cfd7}\n\"debian9.opensips2\" {09b11945-d696-409d-b90b-e5f2b5af6c4a}\n\"centos7-ast-16\" {21eaceac-f85e-4622-a52b-c586352aa9eb}\n\"centos7-rtpengine8\" {935a0191-a17e-4c95-8cf4-022f7ad1a398}\n\"centos7.osips3.2\" {e39ddc59-70cc-4bcb-8f6d-3b6bd9e78d3d}\n\"centos7.osips3.2_node2\" {ecb64a86-aa90-4f53-bd12-5bb253d02058}\n<\/pre>\n\n\n\nListing all your running<\/em> VMs:<\/p>\n\n\n\nalexey@amd:~$ vboxmanage list runningvms<\/pre>\n\n\n\nStarting VM (vm remains working even if you log out from host machine):<\/p>\n\n\n\n

The more the better.<\/p>\n\n\n\n
Now I would like to get the IP address of some VM. But there is no any way to do it until we use GuestAdditions<\/a>. I mean that you’ve already started your VM with the appropriate console command and now need to log in via SSH, but you don’t know it’s IP address (e.g. in case of bridged network<\/a> settings of the VM).<\/p>\n\n\n\nTo be able to see VM’s IP address from host’s machine console, you have to install VitualBox to your guest<\/em> machine. Then you need to “insert” an .iso containing GuestAdditions to your guest<\/em> machine (the easiest way is to do it using VirtualBox GUI, but I’m sure there is also a console command). <\/p>\n\n\n\nIf the VM’s cd-rom with this .iso is not mounted automatically, do it manually:<\/p>\n\n\n\n
[root@flexisip ~]# mount \/dev\/cdrom \/mnt\/cdrom\/<\/pre>\n\n\n\nAfter that the .iso’s files are available:<\/p>\n\n\n\n
[root@flexisip cdrom]# ls -l \/mnt\/cdrom\/\ntotal 47008\n-r--r--r--. 1 root root 763 feb 20 2020 AUTORUN.INF\n-r-xr-xr-x. 1 root root 6384 jan 14 2022 autorun.sh\ndr-xr-xr-x. 2 root root 792 jan 14 2022 cert\ndr-xr-xr-x. 2 root root 1824 jan 14 2022 NT3x\ndr-xr-xr-x. 2 root root 2652 jan 14 2022 OS2\n-r-xr-xr-x. 1 root root 4821 jan 14 2022 runasroot.sh\n-r--r--r--. 1 root root 592 jan 14 2022 TRANS.TBL\n-r--r--r--. 1 root root 4029558 jan 14 2022 VBoxDarwinAdditions.pkg\n-r-xr-xr-x. 1 root root 3949 jan 14 2022 VBoxDarwinAdditionsUninstall.tool\n-r-xr-xr-x. 1 root root 7474611 jan 14 2022 VBoxLinuxAdditions.run\n-r--r--r--. 1 root root 9439232 jan 14 2022 VBoxSolarisAdditions.pkg\n-r-xr-xr-x. 1 root root 16895432 jan 14 2022 VBoxWindowsAdditions-amd64.exe\n-r-xr-xr-x. 1 root root 270840 jan 14 2022 VBoxWindowsAdditions.exe\n-r-xr-xr-x. 1 root root 10000520 jan 14 2022 VBoxWindowsAdditions-x86.exe\n-r--r--r--. 1 root root 259 oct 4 2021 windows11-bypass.reg<\/pre>\n\n\n\nNow we need to install GuestAdditions to the guest<\/em> machine (VM):<\/p>\n\n\n\n[root@flexisip ~]# cd \/mnt\/cdrom\n[root@flexisip cdrom]# sh .\/VBoxLinuxAdditions.run \nVerifying archive integrity...

alexey@amd:~$ VBoxManage guestproperty enumerate centos-flexisip<\/pre>\n\n\n\nBut this command still does not show the IP address of the VM, though it shows its MAC:<\/p>\n\n\n\n
alexey@amd:~$ vboxmanage showvminfo centos-flexisip<\/pre>\n\n\n\nAfter this you may unattach an .iso from your VM cd-rom.<\/p>\n","protected":false},"excerpt":{"rendered":"
