Drive configuration for small virtualization

I do IT infrastructure support primarily for small businesses (up to ~50 users). The past few years I have been doing some server virtualization for situations that don’t require a second physical machine, or for consolidation when it comes time to replace old physical servers. 90% of these environments are something like a Windows SBS server and another 1 or 2 Windows servers, usually to run some line-of-business application, accounting software or whatever else doesn’t […]

Guest Access in QEMU-KVM

I am having trouble in accessing my Guest OS running on QEMU-KVM. However, I noticed that the Guest OS is capable of accessing Host OS easily thru telnet; basically every IP address appear in ifconfig is accessible by Guest OS. The other way around, is not possible. Everytime I tried to access IP address generated from Guest’s ifconfig, it said something about address is unreachable. For your information, I have set up the bridge connection, […]

64-bit Linux hosted on a Mac

From what I can tell, VirtualBox does not have a 64-bit binary for the Mac, and VMWare does not provide a Player build for MacOS. Are there any virtualization options for running a 64-bit guest OS on a Mac host? VirtualBox will run 64bit guest operating systems on MacOS X. See http://www.virtualbox.org/manual/ch03.html for more info. Check more discussion of this question. Bookmark on Delicious Digg this post Recommend on Facebook share via Reddit Share with […]

Linux-KVM networking advice?

Being new to virtualization in general, and somewhat new to Linux (using Debian Squeeze and coming from BSD) I have a hard time understanding what would be the best network bridging option for my host machine. Much -if not all- of the information on the net seems somewhat outdated. There is info on br0, tun, tap and vnet and the like. I’m pretty much lost on what they all mean and do and would appreciate […]

OpenSource VM Servers

I want to get people’s opinion on OpenSource VM software. What options are there to host Virtual Servers? What are the positives or negatives? Do you need a dedicated employee for it? I highly recommend Proxmox: http://pve.proxmox.com/wiki/Main_Page It offers OpenVZ or KVM guests, has a pretty decent web-based admin interface and you can easily cluster hosts so that they can be administered from a single web-based interface. I wouldn’t say you need to dedicate an […]

MSSQL: separate dev and prod databases as separate instances on shared hardware?

I’ve got a small virtualised environment which hosts a small internal website with database backend. I’ve currently separated my webservers and database servers on separate VMs running on the same hardware. However, I’m wondering if a better strategy might be to consolidate the dev/prod database servers onto the same VM(s) but using separate instances? I’m using SQL mirroring for redundancy, so I’d theoretically go from 4 SQL VMs down to 2. Advantages would be fewer […]

Performance implications of running SQL Server 2008 in a virtual machine

I have a bare-bones Windows 2008 R2 Enterprise production server running SQL Server 2008 R2 Enterprise. We have a faster server that isn’t being utilized and I’d like to move the production database onto it. However, I also wanted to use the faster server for something else, so my IT dept suggested building the machine as a XenServer and loading it up with 2 VMs. The second VM isn’t resource intensive, so I’m not concerned […]

How to get the outside world to see Windows Server 2008 R2 web sites?

Newbie, so bear with me here, but I’m looking to install Windows Server on a VM at home. I’d like to make the websites visible to the outside world via IIS. How do I go about doing this? I’m aware that DynDNS will help me to create a URL that constantly points to the right IP. From there I’m not sure exactly how to proceed. Thoughts? You would need to open port 80 in your […]

How can I build a Linux proxy with maximum chances of recovery in case of hardware failure?

I’m ready to install our new proxy (Ubuntu LTS 10.04) and I’d like to set it up so I can recovery it easily and fast in case of any hardware failure. I thought about using esxi and backupping the virtual machine when the configuration is ultimated and use it in case of failure. Is it a good idea? Otherwise I’ve heard of remastersys… Can it be used to achieve such a result? I am sorry […]

Why does a 32-bit server support 32GB RAM?

I just got an old IBM x445 with 4xXeon and 32GB RAM home. I happily put in Win2008R2 DVD but got a bit surprised when it said the system only has 32-bit CPU. A quick Google confirms that. What does a 32-bit system use more than 3-4GB RAM for? Can the OS run 10 4GB processes? Or does the process need to have explicit PAE support? What can I do with this box? I want […]
