I have a Dell's Machine with High on Resources like (32 GB RAM, 24 cores of CPU and 5 TB of Disk Space).
I have installed Openstack(devstack) on this Machine which has Ubuntu installed on it and has IP address 10.10.1.3.
This machine is in our local network , means i can ssh directly to this big machine from my laptop if i am in same network.
Now i have created a virtual machine instance using openstack and it has Ubuntu on it and it has IP address 10.10.0.3.
Now i want to access this virtual machine directly from my laptop like i access the big machine.
Any solution for this?
If your vm (let's call it "instance") is on a internal network (tenant/project network) what you need is a FIP (floating IP) from your external network so you can assign that FIP to your openstack instance. Also ensure your security groups allow ssh to your vm !.
I have some questions here so I can help you a better way:
Do you have an external network already created (flat or vlan based) ?.
The vm is using a tenant/project internal (gre/vxlan) network ?
Did you create a router in your tenant, which is using the external network for external access ?.
The aforementioned router is already connected to your internal network ?.

I want to isolate the hyperv vm machine network from my local machine. I do not want hyper vm machine to see what other machines are in the same network when I do IP scanning from VM.
After creating the VM, you connect it to a virtual switch. That virtual switch is assigned to a NIC. That NIC connects to the internet and not your local LAN.
You can connect it to the internet via a dedicated connection or any number of other mechanisms. You're simply creating a second, independent network.
If you want the VM to use your LAN and a common internet connection, you'll have to resort to using a firewall.
I'm having trouble creating a network link between my Hyper-V host machine and its VM (both are running Windows 10).
I created an virtual external switch for both the host and VM so that both can access the internet and download programs and Windows updates, but I could not get them to communicate with each other directly. My research told me to create a virtual internal switch in Hyper-V and then have the devices be able to access each other that way (presumably by doing something like typing \\host_machine_IP\c$ into an explorer window once the network connection had been made). But once I created the virtual internal switch and assigned static IP address to both the host and VM on it, I still could not ping the host from the VM, or vice versa.
Am I missing a step? Let me know what more details you guys need.
By default you would have Windows Firewall blocking your communications until you confirm network profile to be other than Public. Try selecting a home\work network location profile via Control Panel > Network and Sharing canter. Or disable the firewall on the machine you try connecting to. Otherwise you should have no communication problem with the setup described, provided the subnet is the same for both machines.
I have a dedicated virtual debian server running with my website, and now have a copy of that so that I can try some configurations by running it virtually on my own PC. It runs fine, but I'm unable to access the machine through http.
The problem is that my machine has a fixed ip, something like 194.247.x.x . My home network however has computers in the range of 192.168.1.x
Is it possible to not change anything in my virtual machine and still configure vmware networking so that I'm able to access the websites it's running?
The only way I can see this happening for you is to use NAT (Network Address Translation) between your home network and your VM.
To do this, you could use a free software based router - something like Vyatta (www.vyatta.org) - and create a VM with two NICs - one with an IP on your home network, and the other with an IP on the same network as your VM. You then configure NAT to translate your home IP to your web server IP and then you're done.
There's nothing 'de-facto' VMware that will allow you to do this (other than using vShield - which will do NAT'ing anyway)...
I have a windows 2003 VM running on my windows xp machine.
The machine name of the VM is itdom.domain.com
The windows xp host machine is disconnected from the LAN.
I want to be able to connect to the VM from the host and vice versa using there computer names. For example the URL http://itlab.domain:7080/domainsm must be accessible from the host computer.
Is there any configuration that I can do on any of the machine to do this.
Just because you have no physical network connection doesn't stop you setting up networking on the host and guest machines. One way of doing this is to add an IP address to the host machine's physical network port and create a bridged network on that port so that the guest can also see it.
You don't say which VM technology you are using, but in many of them you can setup an internal network between the host and guest. All you need to do then is edit each hosts file to add a hostname for the IP address of the other machine. You may also need to configure firewalls to allow access between the two.
No doubt there are also other ways to achieve this.
I am using Virtual PC 2007 with Windows xp Pro as the Guest.
Is it possible to add the Virtual PC to the network of the guest PC and to the domain of the Guest PC?
I enabled NAT shared networking but that only allows internet access on the guest..
Thanks
This shouldn't be a problem when you add the guest to host's physical adapter:
In the settings for your VM, go to Networking and instead of "Shared networking (NAT)", select the NIC that's connected to the network on your host (e.g. "Realtek RTL8116 Gigabit Ethernet", or whatever your NIC is; this is equivalent to VMWare's Bridged Mode). That way, the guest will appear as a real computer on your network, and will work like a physical box on the network.
IIRC, MS VPC bypasses the default Windows firewall on the host, so only the guest's firewall applies; for other FW products, you may need to enable something like "permit packets not destined for this host".
Just to add to the above answer-
1.
Inside the Local Area Connection
Properties- VM Network Services Driver
wasnt installed without which the NIC
option wont appear in the Virtual
machine Network Adapter Configuration.
I reinstalled the Virtual PC and that
entry Virtual Machine Network
Driver appeared.

Shouldn't be a problem as long as you can connect to a domain controller from the virtual computer.
If you know the IP address of a domain controller, try to ping it. Then try to ping it using the computer name, to see if name resolution is working correctly. What happens when you join a domain using Control Panel | System. Do you receive an error message?
I have not used Virtual PC, only VMWare workstation on Linux, so I do not know how the networking setup is on Virtual PC. On VMWare, you can choose between bridged and NAT networking for a virtual machine. I have been able to set up Windows guest computers as members of a windows domain using both kinds of network setup.
