  • virtual machines: optimal host os to run Windows XP guest os?

    - by user61132
    My department doesn't have the budget to upgrade my ailing Dell D620 laptop. However, I do have the option to buy my own personal computer, then use my company-issued ISO image to run Windows XP as my guest os using virtualbox or vmware. Therefore, last month, I bought an Acer AX3910-U3012 desktop that had Windows 7 as the host os (and 8G RAM). In short, I was disappointed with the performance while trying to run WinXP as the guest os. (It didn't perform much better than my laptop.) Just wondering what the optimal host os would be for running Windows XP as the guest os? (No, I can't use my company-issued ISO image to build the os for my personal computer.) FWIW, I'm willing to spend up to $2k if it's REALLY worth it, but would prefer to spend no more than $1k. Also, in an effort to cut costs, I'd prefer buy a desktop instead of a laptop. Thanks for any/all feedback.

  • Sandboxie or VHD for virtual environment?

    - by lucian.jp
    I am looking for advices about creating virtual development environment. Is it better to have a base VHD file with differential VHD for stable development environment and another differential VHD file for beta development environment or should I install Sandboxie 64-bit and install both environment in different sandbox? I am concern about windows services and shortcuts with the sandbox. Current OS : Windows 7 64-bit

  • Two virtual computers using one laptop?

    - by JP19
    Hi, I have a laptop and an external display. I am able to use the external display either as extended desktop OR duplicate desktop. I also use a separate keyboard and mouse. So effectively, the laptop acts just as a box without display. I want to know is it possible to use the laptop as 2 virtual PCs. (with separate control). I.E., one person uses the laptop as a laptop, and other person can simultaneously connect a keyboard and mouse and the external display and effectively get a second PC. OS I am using - windows (thought solution for other OSes are welcome). Laptop is a Dell Precision M6300. thanks JP

  • Missing Data on VMWare Virtual Disk

    - by Lachlan McDonald
    Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

  • Physical-to-virtual for personal use

    - by Journeyman Geek
    One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?

  • VPN/AFP server for centralized TimeMachine backups

    - by Keith Johnson
    I am a sysadmin for a small group of about 7 people who prefer Apple machines for their work. These machines are currently either a) not backed up at all, or b) backed up using Retrospect(Which I'm not very fond of). I don't really have the budget for anything fancy, and I'd like to keep it as user friendly as possible. Ideally I am thinking of a VPN server they can connect to(to keep the traffic secure, and because they work from home frequently) along with an AFP server for use with TimeMachine. The goal would be to get better backup coverage, along with user-initiated restores and overall ease of use. Does this seem like a reasonable idea? Has anyone done this before? Are there any obvious problems I've overlooked?

  • Why Virtual Box won't give me option to create 64 bits guests?

    - by Eduardo Born
    My host is x64 bits Windows 8.1. I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64). When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS... Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course. Here is what I tried so far: I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command: VBoxManage modifyvm [vmname] --longmode on for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason. I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here? Thank you very much!! Eduardo

  • How to make TimeMachine back up contents of any path or mounted volume

    - by Olfan
    I keep different types of data in different encrypted sparsebundle images (say, one for each client) which automatically mount upon login but can't be opened by anybody other than myself. So, after login I have a number of virtual volumes in /Volumes/ which keeps my client data both secure and organized. How do I include data inside these virtual Volumes in TimeMachine's backups, or data residing in any path on any partition/volume? I found a promising solution description at blog.eurocomp.info involving editing the com.apple.TimeMachine.plist but all I can get TimeMachine to do is backing up the sparsebundle files themselves. I want it to back up the files inside the mounted image, though - something like adding /Volumes/Client_abc/ to TimeMachine's search path. Please do not redirect my to this previous question as it doesn't solve the problem at all. Please also refrain from telling me why you think I should not want this answer as that will not solve anything either. Please lastly don't say "it can't be done" unless you can technically prove that claim.

  • Mac Parallels - Bridged network

    - by Jack
    I am new to Apple and my task is to install VMs on a Mac server. I am trying to install 4 VMs and I want them to have separate IPs and be visible on the network as separate machines. What are my options? My research shows me that I can use a bridged network, but I have to select an adapter. I have only two network adapters, does that mean I can only have 2 VMs? And when I configure the 2 VMS, will my actual server have internet connection? Or does it use the Mac's address?

  • VMware - I/O error - how to fix?

    - by Maya-G
    I'm running XP pro on VMware - it mounts and runs just fine. However, if I power down the VM and try to copy it, or even if I try to do a simple Mac Backup (using Carbon Copy Cloner), I get an i/o error at one very specific VMDK file. Here's a sample of the error - this from CCC: "12/20 22:49:30 Detected input/output error 12/20 22:49:33 rsync: read errors mapping "/Users/blahblah/Documents/Virtual Machines.localized/WindowsXP-Professional150G.vmwarevm/WindowsXP-Professional150G-000001-s065.vmdk": Input/output error (5)" How can I regain my ability to do backups of my Mac without this I/O error?

  • VMWare Workstation Linux Host performance tuning

    - by Hoghweed
    I need to improve my linux hosted vmware workstation for using multiple virtual machines at the same time. I feel very stupid I lost a great blog post link which I found last month (and I'm not able to find it again..) so I try to ask here if anyone can help me: This is my host (laptop): 16GB DDR3 Ram HDD Hybrid 750GB 7200 (8GB SSD Cache) Mint 15 x64 Kernel 3.9.7 swappiness set to 10 The above are the important things about the host. So, My need is the ability to run 2 or 3 VMs at the same time. The lack of performance is about the disk, The last time from that blog post I lost, I setup /tmp to be mounted ad a memory partition and in my previous installation that was good, now I'm not able to find a good solution to tweak the things. I think with 16GB o RAM there will be no problems to run multiple VMs, but whe they start to swap or use the /tmp things going bad (guest cursor going too fast after a freeze, guest freeze and so on) Anyone can help me to fit a good host tweak and configuration to get better performance? Thanks in advance

  • What is the best VM for developing WPF apps from within OS X?

    - by MarqueIV
    All of my machines are Macs (Mac Pro, MacBook Pro, MacBook Air and Mac Mini (and Apple TV 2.0 too! :) ) but for my day-job, I develop .NET/WPF applications. Normally I just boot into Boot Camp and develop that way, which of course works great, but there are times when I need to simultaneously get to things on my Mac-side of the equation, so I've bought both VMware 3.1 and Parallels 6. Both work, however, even on my Mac Pro where I paid to upgrade to the better video cards (the NVidia 8600s I think vs. the stock ATI cards) the WPF performance bites!! Now this confuses me since both boast that they support not only hardware-accelerated OpenGL 2.1, but also hardware-accelerated DirectX 9 (VMware even allegedly supports DirectX 10!) via their respective virtual drivers and both can run 3D games just fine, even in a window. But even the simple act of resizing a WPF window that has a tiled background results in some HIDEOUS repainting and resizing behaviors. It's damn near closer to what you'd expect over RDP let alone a software-only renderer (forget accelerated hardware completely!) So... can anyone please tell me WTF WPF is doing differently? More importantly, how can I speed up the WPF performance? Should I switch to VirtualBox that also has support for DirectX? Or am I just gonna have to 'byte' the bullet (sorry... had to. So I like puns! Thank Jon Stewart!) and continue using Boot Camp?

  • How do you add more space to a Fedora (LVM) partition?

    - by Trevor Boyd Smith
    In a nutshell, i have a VM that ran out of space. I increased the size of the VM's harddrive to be 4 times bigger but the OS partition is still only using 1x the space. I need to change the LVM partition to take up the extra 4x space but I don't know how to extend the LVM partition. (NOTE: To make the screenshots given below I had to boot from a live-cd for gnome-partition-manager (aka gparted). Very unfortunately gparted is only able to "detect LVM" and can't do any LVM operations.) Here is what "gparted" shows. Please notice that the "resize" option is not available: The Problem: I can't find good directions<1 on how to grow the LVM partition via GUI or command-line! How do you grow a LVM partition that was created by the default Fedora install? If you are giving command line directions. Please explain what each line of commands does.

  • Virtual machines with failover setup

    - by kimmmo
    We have three servers and our plan is to run a number of virtual machines on them in such manner, that if one of the nodes blow up, we can either quickly or seamlessly get a spare running on another node. In addition to the normal networking, they're interconnected via dual 10Gbit NIC's, so networked raid/mirroring shouldn't be a problem. The guest VM's are mostly going to be running text mode linux, but of course it wouldn't hurt to be able to spin up a non-mission critical windows guest for running Visual Studio or checking IE compatibility of a web app. We've spent some time trying to get some magical cloud setup running using Stackops and Crowbar but it started to look like they were offering way too much and were too complicated for our needs. The next candidate, I think, is Ubuntu 11.04 server + KVM + Ganeti + Drbd, unless you can come up with a suggestion for a better solution that we have missed. Requirements: Installation should be simple or at least understandable without being in the dev team A browser interface for creating and managing VM's is a nice bonus Single node's hardware failure should cause minimal downtime for VM's that were running on that node Adding more nodes should be possible without shutting down the VM's.

  • Managing disk in a VM

    - by dst
    I'm replacing my two old rack servers with a new one that has plenty of power to take over the functionality my current servers. The server is a 4U rack mount with 16 3.5" SAS drive bays, two 2.5" bays, a Xeon E3-1230v2 CPU and 32GB of ECC RAM. My issue is the following. I would like to have a FreeBSD file server with ZFS managing disks. However, I need other VMs for e.g. a shell/git server, mail server etc. I'm wondering how to deal with the following issues: I want ZFS to fully manage the disks, so I'm not using any hardware RAID. Should I pass the SAS controller directly to the FreeBSD system as passthrough PCI? I want to maximize the reliability of the setup. On what disks should I install the hypervsor and keep server system disks? For (2) I have the option of having a RAID setup on the SAS controller and using that as system disk to store the hypervisor as well as VM images. However, this makes PCI passthrough to the file server impossible. Another option is using the two 2.5" bays. In terms of reliability how are SSDs compared to e.g. WD RE4 disks? Would it make sense to have two SSDs in software RAID as boot disks for the hypervisor or should I just go with e.g. WD RE4 disks in a software RAID setup. I also need to think about where to store the mails for the mail server, but this could be done over NFS between the VMs. BTW, this is for home use, so the load is not really that big. What I'm looking for is best practices for splitting up a server.

  • Setting up a Network Bridge on Linux VM (Windows 7 Host)

    - by GrandAdmiral
    I would like to use NetEm to simulate a low bandwidth environment while testing an Internet-connected device. My plan is to setup a bridge in a Linux VM (Linux Mint 13) on a Windows 7 host. Unfortunately I'm having trouble setting up the bridge. Then I can use NetEm in the Linux VM to limit the bandwidth to an external device. I went with the following script: ifconfig eth0 0.0.0.0 promisc up ifconfig eth1 0.0.0.0 promisc up Then create the bridge and bring it up: brctl addbr br0 brctl setfd br0 0 brctl addif br0 eth0 brctl addif br0 eth1 dhclient br0 ifconfig br0 up When I run that script, I see the following warning: Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service smbd reload Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the reload(8) utility, e.g. reload smbd The device connecting to the bridge is able to obtain an IP Address, but it can only ping the IP Address of the bridge (both are 10.2.32.xx). Then after a few minutes, other parts of our network go down. I'm not sure why, but once I kill the bridge the network is fine. Is it possible to setup a network bridge in a Linux VM? Do I need to do something else with the dhclient br0 part of the script? By the way, I'm using VirtualBox. The wired connection is eth0 and the wireless connection is eth1. The wired connection is connecting to the device and the wireless connection is going to the network. Both adapters are set up as bridged adapters with promiscuous mode set to "allow all".

  • Keyloggers and Virtualization

    - by paranoid
    Whilst pondering about security, and setting up different VM for certain online activities deemed more risky or requiring extra security (banking, or visiting untrusted websites, etc), I came to think about how such a setup (different VMs for different uses) would defend me against a keylogger. So, two questions then: 1: If a keylogger has been installed inside a VM, can it capture data outside its own VM? 2: The opposite, does a keylogger in a host capture strokes typed within a VM residing in that host? My bet would be No and Yes respectively, but I really have no idea. Anyone else does?

  • Is it possible to add an existing Azure VM to an Azure Virtual Network?

    - by Dan Harris
    Didn't think this was directly related to programming, so thought Superuser would be better than Stack Overflow.... Is it possible to add an existing Azure VM to an Azure Virtual Network if you didn't add it to the virtual network at the time of creation? I can't see an option to change which Virtual Network the VM is connected to. Do you just have to do it at the time you create the VM, and if you don't do it then you will need to re-create the VM and delete the existing one? Example of the scenario: No VM's or Virtual Networks exist I create a VM (VM1), there is no virtual network so it isn't added to one Later I create a Virtual Network in Azure (Network1) It is possible to create another VM (VM2) and connect it to the Virtual Network (Network1), but can I connect VM1 to Network1 or must I delete VM1 and re-create it to get it connected to Network1?
