Yes, for sure.

machines?

Again, yes. You can reach your servers as if they were physical ones. Managing your machines will be even simpler as you won't have to deal with hardware driver related issues.

3. would the ip address of host be shared or could each vm get its own?

You have the choice for this. You can configure several virtual switches depending on your needs ; a virtual switch can be shared between the host and his VMs, it can be private or it can be shared between the VMs only.
When you setup a virtual network card for your VM, you 'plug' it to one of the switches you configured. In your VM, you will see a network card that you can configure as you want (DHCP or not, etc...).

I don't have any but I'm sure you can find some useful examples just by googling.

When you configure your VM you can assign it the number of cores you want to, as well as tha amount of RAM that it will use.

That sure sounds like a bad debug dump since it provides no useful information. Usually internet explorer has a "safe mode" that it can be run as, try running it in safe mode, if it works, then theres a plug-in causing the crash. At that point, your best option is to just uninstall all the plugins and start fresh. If that doesn't work, you may have to download and install a fresh copy of internet explorer (current version is 9) or try using another browser such as Firefox or Opra.

I would search for complementary modules attached to IE, and deactivate/uninstall any that would seem suspicious to me.
Also a little Windows Update trip could make things in order.

Try clearing your browser history and Internet Temp Files. Is the pop-up blocker enabled, or is it trying to reuse the existing window?

Make sure the "reuse windows for..." is unchecked in the advanced tab under Internet Tools.

Let us know what you find.

Hi,

I have a windows server 2008 machine.

I want to install linux operating system on it to have both a up-and-running the same time, therefore I am looking for a FREE and good virtual machine tool?

what's your recommendation please?

Thanks..

I second VirtualBox. I use it at work (on a Windows host) and home (on a Linux host) and it does everything I need.

I recommend VirtualBox, too. I run it on a Mac without issue. Just be sure to install the kernel headers in Linux before you install the guest additions.

I am already using Virtualbox now and it's good except one issue..

Serial port is not working on the guest..

I am connecting a serial to the server to read the PBX data and I want to collect it from the guest linux machine but it doesn't recognize the serial?

From the VirtualBox help file:

3.9. Serial ports
VirtualBox fully supports virtual serial ports in a virtual machine in an easy-to-use manner.[16]

Ever since the original IBM PC, personal computers have been equipped with one or two serial ports (also called COM ports by DOS and Windows). Serial ports were commonly used with modems, and some computer mice used to be connected to serial ports before USB became commonplace.

While serial ports are no longer as ubiquitous as they used to be, there are still some important uses left for them. For example, serial ports can be used to set up a primitive network over a null-modem cable, in case Ethernet is not available. Also, serial ports are indispensable for system programmers needing to do kernel debugging, since kernel debugging software usually interacts with developers over a serial port. With virtual serial ports, system programmers can do kernel debugging on a virtual machine instead of needing a real computer to connect to.

If a virtual serial port is enabled, the guest operating system sees a standard 16550A compatible UART device. Both receiving and transmitting data is supported. How this virtual serial port is then connected to the host is configurable, and the details depend on your host operating system.

You can use either the graphical user interface or the command-line VBoxManage tool to set up virtual serial ports. For the latter, please refer to Section 8.7, “VBoxManage modifyvm”; in that section, look for the --uart and --uartmode options.

In either case, you can configure up to two virtual serial ports per virtual machine. For each such device, you will need to determine

what kind of serial port the virtual machine should see by selecting an I/O base address and interrupt (IRQ). For these, we recommend to use the traditional values[17], which are:

COM1: I/O base 0x3F8, IRQ 4

COM2: I/O base 0x2F8, IRQ 3

COM3: I/O base 0x3E8, IRQ 4

COM4: I/O base 0x2E8, IRQ 3

Then, you will need to determine what this virtual port should be connected to. For each virtual serial port, you have the following options:

You can elect to have the virtual serial port "disconnected", which means that the guest will see the device, but it will behave as if no cable had been connected to it.

You can connect the virtual serial port to a physical serial port on your host. (On a Windows host, this will be a name like COM1; on Linux or Solaris hosts, it will be a device node like /dev/ttyS0). VirtualBox will then simply redirect all data received from and sent to the virtual serial port to the physical device.

You can tell VirtualBox to connect the virtual serial port to a software pipe on the host. This depends on your host operating system:

On a Windows host, data will be sent and received through a named pipe. The pipe name must be in the format \\.\pipe\<name> where <name> should identify the virtual machine but may be freely chosen.

For forwarding serial traffic, you can use a helper program called VMware Serial Line Gateway, available for download at http://www.l4ka.org/91.php . This tool provides a fixed server mode named pipe at \\.\pipe\vmwaredebug and connects incoming TCP connections on port 567 with the named pipe.

On a Mac, Linux or Solaris host, a local domain socket is used instead. The socket filename must be chosen such that the user running VirtualBox has sufficient privileges to create and write to it. The /tmp directory is often a good candidate.

On Linux there are various tools which can connect to a local domain socket or create one in server mode. The most flexible tool is socat and is available as part of many distributions.

In this case, you can configure whether VirtualBox should create the named pipe (or, on non-Windows hosts, the local domain socket) itself or whether VirtualBox should assume that the pipe (or socket) exists already. With the VBoxManage command-line options, this is referred to as "server" or "client" mode, respectively.

For a direct connection between two virtual machines (corresponding to a null-modem cable), simply configure one VM to create a pipe/socket and another to attach to it.

You can send the virtual serial port output to a file. This option is very useful for capturing diagnostic output from a guest. Any file may be used for this purpose, as long as the user running VirtualBox has sufficient privileges to create and write to the file.

Up to two serial ports can be configured per virtual machine, but you can pick any port numbers out of the above. However, serial ports cannot reliably share interrupts; if both ports are to be used at the same time, they must use different interrupt levels, for example COM1 and COM2, but not COM1 and COM3.

You can use VMWare Server http://www.vmware.com/products/server/overview.html[^]
I use it and it works great.
I run it on a win7 x64 PC (AMD quad core, 12 GB RAM) and it hosts my virtual Win2008R2 server - x64, (where I have my web server, ftp, email server, sharepoint server), a Linux server, a Linux Ubuntu (which I use as a virtual linux desktop) and a virtual WinServer 2008R2 (configured as a desktop development machine). It works 24/24, 7/7, for almost 18 months now, and had no problems with it.

Definitely VirtualBox. I've used it for years to write Linux code on a Windows machine. It's easy to install the guests OSs on it. The Guest additions (which I highly recommend) are pretty easy to get goign in the last year. The one gotcha is that you need to do a separate install of the VirtualBox Extension Pack. Documentation is OK, too.

I've mostly used Ubuntu and Fedora on it.
