I want to shut down the host OS (CentOS7) when exiting KVM.
Is this function available in virt-manager?
Or is it possible to shut down the host OS when shutting down the guest OS in some other way?

I have a standalone VM Host running Esxi 6.7 with 9 VMs host running on it. between these 8 VMs there is VCSA Machine that requires me to put host into maintance mode.
i can't shutdown the VCSA to put the host in maintaince mode (i can do it from the Esxi web interface but then i lose the control from VCSA which i need to run the updates)
There is no way to put the host in maintenance mode while a VM is running.
The host is in a state of Entering Maintenance Mode until all running virtual machines are powered down or migrated to different hosts

I'm truing to run a django server and all of a sudden I'm not able to go
to localhost:8000. I was able to a few seconds back, but now now it's just freezing up and saying "waiting for localhost"
I'm on a Mac OS X
How do I debug this?
Some links:
Waiting for localhost : getting this message on all browsers
Waiting for localhost, forever!
Why does my machine keeps waiting for localhost forever?
To summarise it - in general it means that the 1) server is waiting for input (e.g. not returning a response), 2) some other service might be running on the same port, 3) no DB connection.
However, that said a restart should sort all these out by killing all processes that might've taken the port and by restarting the DB and reconnecting properly.
I have installed Cent OS 7 inside my vmware and selected the network type as NAT. Everything is fine. The ip assigned to vmware cent OS is 192.168.137.130. I am able to connect to 192.168.137.130 from outside that means from my windows os on putty via port 22. I am able to ping. I am able to telnet to port 80 (httpd is running). But I am unable to connect via browser to 192.168.137.130.
192.168.130.1
When I type this I am able to connect to my windows webserver. What I have done wrong. Please help.
I have a database server that is started from a VirtualBox VM. I can start my development only after the dataBase VM boots up. How can I check whether the dataBase server has been booted up successfully. I am well aware of the command VBoxManage showvminfo
but it shows the State as 'running' itself even when the VM is still booting up.
Is there a way to check the booting status?
I suspect not, as even the Vagrant project seems to use a constantly-retrying SSH connection with a large timeout to determine if the machine is ready.
Okay so I have my actual laptop which has vmware player installed. I am running lubuntu as a virtual machine and I installed django on the virtual machine and am testing my app so I did python manage.py runserver and I can access the app by visiting 127.0.0.1:8000 from my VM, however, If I go to 127.0.0.1:8000 from the actual computer (not the VM), it says 'chrome could not connect to 127.0.0.1:8000'.. Any idea how to fix it?
You can try running the server on 0.0.0.0
python manage.py runserver 0.0.0.0:8000
The IP address 0.0.0.0 means "all IP addresses on the local machine" (or all IPv4 addresses on the local machine).
Next, you will need the ip address of your VM. Visting http://<ip_address_of_vm>:8000 on other computers should access the django development server on your VM.
Note: If your VM only has an internal IP (e.g. 192.168.x.x) then only computers on the same network can visit the VM.
I was able to get #Kerberos answer to work. (not enough points to comment so I'm adding it as a seperate answer).
I am running Ubuntu 12.04 LTS in a guest OS in VMWare. The host laptop is running Windows 8.
As mentioned by Kerberos, in VMWare, go to Player ==> Manage ==> Virtual Machine Settings...
On the Hardware tab, select Network Adaptor, then select the radio button for Bridged: Connect directly to the physical network. Select OK
In the VM, the network connection information should now have the same IP address of the host OS internet connection. In my case: 192.168.1.141 (yours will vary).
In the VM, start Django using python manage runserver 192.168.1.141:8000
Using this method, I am able to access the webserver running in the VM at this IP address from within the VM, from host machine, and from other systems on the same 192.168.1.xxx network.
to access virtual machine (guest) from outside the host computer, you have to set the guest network mode to bridge
Bridge-mode connects the guest to the actual network so that other machines can connect to it
