My Linux VM (libvirt virsh), running within a CentOS 5.8 Linux server, stopped responding. I cannot ping it, and I cannot connect to it. I need an expert to fix it. The problem started when we migrated our domain controller, DNS server, and DHCP server, from Windows Server 2003 to Windows Server 2012. Something with that Windows migration caused my VM to stop responding in our internal network at work (5 servers, and 20 workstations total). The parent Linux server has the correct settings for default gateway and DNS settings. And, I can connect to the parent Linux server just fine. Key skills needed to do the job well: knowledge of how a Windows server migration on the same network may adversely affect a linux virtual machine. Also, expert experience and knowledge of libvirt virsh on Linux. Successful engagement will be a screen share meeting, where you can have access to the Linux server, and the Windows server, as needed.

We have a product that needs to be implemented in a large company. The product uses MS SQL Server as its database and is a winforms application developed using Visual Studio. Remote Access to the application is required across the country and a solution suggested is a thin client application server like RemoteApp / Citrix. We need a very experienced person who can help us size the servers, design the network for optimal performance with remote access and also document the setup professionally.

We are looking to move our Amazon EC2 instances into a VPC. We have created a test VPC environment with 1 public subnet, and 3 private subnets. Successfully created a VPN connection from our office to the VPC in which we can ping and nmap the private IPs of the instances in any of the subnets. The issue that we are having is that even though we can see that port 22 is open, we are unable to connect (SSH) to any of the machines through their private IPs. Therefore, we are looking for someone who can take a look at what we've done and fix any issue that would prevent us to access the machines from a VPN connection.
