  • Moving a VM from MS Virtual Server R2 to VirtualBox

    - by AngryHacker
    I have a Windows 2000 Professional VM happily running under MS Virtual Server R2 on WindowsXP. I need to move it to a different PC and the only one available is a Mac with VirtualBox on it. Theoretically, VirtualBox accepts .VHD files out of the box, but my attempts to run my VHD on VirtualBox resulted in failure. The Guest OS just keeps rebooting. I've attempted to get help on the VirtualBox forums, and they said that the VM image must first be prepped for the move, but could not give me any specifics. Anyone here know what is specifically involved in moving a Win2k .VHD to VirtualBox on the Mac?

  • Using Virtual Domains with WordPress and Cherokee Web Server

    - by ikevinjp
    I'm trying to configure WordPress to work with Cherokee Web Server. The multi-site set up in WordPress is yyy.com and uses 'sub-domains'. Thus, I have sites like aaa.yyy.com, bbb.yyy.com - they all work fine so far. However, I have another completely different domain: abcde.com. Within WordPress, the sub-domain set up is abcde.yyy.com. When a public user accesses abcde.com, it cannot properly be redirected to the WordPress sub-domain abcde.yyy.com. How do I set up Cherokee to properly redirect virtual domains to WordPress? That means, the domain facing public would be abcde.com but WordPress would want to see abcde.yyy.com to properly return the correct content for the specific site. (I tried and it always get redirected to something like this: "http://yyy.com/wp-signup.php?new=abcde.com")

    - by noname
    The following was my deployed servers: client ------ nginx proxy(example.com) ------ back-end server(192.168.1.20) The nginx proxy's external URL was configured under a virtual directory http://example.com/demo/ The back-end server was configure to http://192.168.1.20:8080/ the following was part of the nginx configure file: location /demo { proxy_pass http://192.168.1.20:8080/; proxy_redirect default; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } When the back-end server send a redirect response (HTTP CODE 302) with LOCATION head field "http://192.168.1.20/subdir/", the nginx map this LOCATION header field to "http://example.com/subdir/", not the disired "http://example.com/demo/subdir/"

  • Virtual Server 2005 R2 kungfu

    - by AngryHacker
    Does Virtual Server 2005 R2 have a command line interface, that's versatile enough? Here is a situation. I run a Win2k VM on an old memory constrained machine. I allocate it 378MB of RAM and the VM runs just fine. Once a month, inside the VM, I backup the (a very large) database, compress it using 7Zip and ftp it to the backup site (all in a script). Unfortunately the compression part takes a massive amount of RAM (far exceeding the 378MB), it goes for the paging file and brings absolutely everything to a crawl and literally takes 2-3 days, if left unattended. So to fix this, I have to shutdown the VM, give it temporarily 768MB of RAM and then the whole thing finishes in 20 minutes. So, is there a way do the following automatically from the host machine in a script? Shutdown the guest OS (I think, I got this part) Change the RAM allocation from 378 to 768 Start the guest OS again then, 1 hour later, do everything in reverse.

  • Windows Azure virtual machine credentials

    - by Georges
    I have created a Windows Server virtual machine, and this also automatically created a disk (VHD). Then I removed the vm, and I created a new vm from the same vhd: in this process I wasn't asked to supply any credentials. I am not able anymore to login (with rdp) to the new VM, the credentials that I supplied when creating the first machine don't work anymore. Any ideas why this happens? What credentials should I use? Thanks a lot in advance.

  • Virtual Box - not filling entire screen

    - by jdavis
    I am new to VirtualBox and am trying to set up an instance of Windows 7 64. I have the virtual machine instance running with Windows 7 now installed, but it only fills up a small portion of my screen. Even when I go full screen, the window stays the same size and the rest of the screen is filled with gray space. I have installed VirtualBox Guest Additions, which allowed me to go from a resolution of 800x600 to 1024x768, but this still isn't satisfactory as my laptop display is 1600x900. Any help on this would be most appreciated. Thanks.

  • Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

    - by snowballhg
    We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions? Thanks

  • DHCP server inside a virtual machine can't see other machines

    - by William
    Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

  • Cherokee high virtual memory usage even after disabling I/O Cache

    - by nidheeshdas
    I've Ubuntu 10.04LTS 64-bit running on a openvz container and Cherokee 1.0.8 compiled from source. The virtual memory usage of cherokee-worker is around 430 MB even after disabling I/O cache from Advanced - I/O Cache - NOT enabled. Is this issue particular to openvz? Because many people reported to have successfully reduced virt memory usage by disabling io cache. htop output: http://imgur.com/z5JEL.jpg (newbies not allowed to post image.) thanks in advance. nidheeshdas

  • Exporting virtual machine from Windows Azure to Amazon

    - by Somebody
    As documentation says: You can import VMware ESX and VMware Workstation VMDK images, Citrix Xen VHD images and Microsoft Hyper-V VHD images for Windows Server 2003, Windows Server 2003 R2, Windows Server 2008 and Windows Server 2008 R2. What about virtual machine with Ubuntu on it? Will it import it successfully? Have anyone tried to do it? Is it possible to import VM directly from Windows Azure. Without need to download VM on my machine and then upload it to Amazon? Thanks.

  • vmware host stuck after adding a virtual drive to client

    - by Saariko
    I use ESXi 5.0 I created a virtual (400GB) drive (located on an iSCSI mapped drive), and tried to add it to a specific client on the host. The task has stopped at 11%. After over an hour, it seems that everything is pretty stuck. Looking at the datastore - it says that 400GB are allocated, but I don't see the new drive with the client. How can I check if the process is still working? or should I restart the host and pray for good?

  • Run Photoshop on VM (virtual machine) to increase calculation power, without violating the licence agreement (EULA)

    - by mecplusultra
    A question concerning the possibility to run Photoshop as VM without violating the licence agreement (EULA) : My Adobe Photoshop is bloody slow, nd sometimes I need to launch thousands of image calculations that have to use hundreds of PSD templates. I want to increase my Photoshop calculation power by creating non-persistent virtual machines on my hosted server. Each VMm would only alive for a few seconds, just enough time to deliver the calculated file. Is this a violation of the EULA? I must clarify that I'm the only one to access my non persistent VMs.

  • Wifi in android-x86 with virtual box [closed]

    - by Abhishek
    I am trying to run android-x86 in Virtualbox, I am using a laptop which connects to internet via WiFi. When the android starts in virtual box, it does not recognize the host wireless connection or in other words does not identify the wireless network at all. So I got a TP-Link wireless USB adapter connected to the laptop and configured wireless controller in USB for the VM. But sadly I found that the wireless is disabled as soon as the Android VM starts. I am stuck on how to let android running in Virtualbox identify my Wifi. Any guidelines or set up instructions would be greatly helpful.

  • Howto setup a `veth` virtual network

    - by Reinder
    I'd like to setup three virtual network interfaces (veth) which can communicate with each other. To simulate a three node cluster, each program then binds to one veth interface. I'd like to do it without LXC if possible. I tried using: Created three veth pairs: sudo ip link add type veth Created a bridge sudo brctl addbr br0 Added one of each pair to the bridge: sudo brctl addif br0 veth1 sudo brctl addif br0 veth3 sudo brctl addif br0 veth5 Configured the interfaces: sudo ifconfig veth0 10.0.0.201 netmask 255.255.255.0 up sudo ifconfig veth2 10.0.0.202 netmask 255.255.255.0 up sudo ifconfig veth4 10.0.0.203 netmask 255.255.255.0 up Then I verified if is works using: ping -I veth0 10.0.0.202 but it doesn't :( The I added IP addresses to the veth1,veth3,veth5 and br0 interfaces in the 10.0.1.x/24 range. But that doesn't help. Any ideas? or a guide, all I find in how to use it with LXC. Or am I trying something that isn't possible?

  • Services of virtual machines

    - by RredCat
    I am looking a way to establish dev machine on the cloud. I want to have access for development from different places. I don't want to play with sync brunch and so on. It would be Lubuntu with 1G or 512M memory and I want to have way to setup my image. What I have found in the current moment: Amazon EC2 service Azure Virtual Machines I am pretty sure that there should be more services like this. I hope to find one specified for this purpose. I have experience to work in such way and I like it. Unfortunately it was server of certain company for projects of this company and I can't use it for my private aims. Could anybody suggest me anything?

  • Integrating virtual keyboard on a HP TouchSmart with an Adobe AIR app

    - by Alan
    Hi, Does anyone know if it's possible to integrate the ToushSmart's virtual keyboard with an Adobe AIR application? In most programs (Internet Explorer, Firefox, etc), when a user touches a text field a little keyboard icon automatically pops up which, when pressed, will bring up the virtual keyboard. However, this doesn't happen when clicking on text input fields in Adobe AIR applications. Has anyone had any experience working with AIR/Flash and touchscreens? Is there any API that can tell Windows (or the HP virtual keyboard specifically) that the user has clicked in a text field and that the virtual keyboard should be shown? The text fields are the standard kind (fl.controls.TextInput). Any suggestions would be greatly appreciated. Thanks in advance!

  • Initialize virtual attributes

    - by Horace Loeb
    I have an IncomingEmail model with an attachments virtual attribute: class IncomingEmail < ActiveRecord::Base attr_accessor :attachments end I want the attachments virtual attribute to be initialized to [] rather than nil so that I can do: >> i = IncomingEmail.new => #<IncomingEmail id: nil,...) >> i.attachments << "whatever" Without first setting i.attachments to [] (put another way, I want this virtual attribute to default to an empty array rather than nil)

  • Virtual member call in a constructor when assigning value to property

    - by comecme
    I have an Abstract class and a Derived class. The abstract class defines an abstract property named Message. In the derived class, the property is implemented by overriding the abstract property. The constructor of the derived class takes a string argument and assigns it to its Message property. In Resharper, this assignment leads to a warning "Virtual member call in constructor". The AbstractClass has this definition: public abstract class AbstractClass { public abstract string Message { get; set; } protected AbstractClass() { } public abstract void PrintMessage(); } And the DerivedClass is as follows: using System; public class DerivedClass : AbstractClass { private string _message; public override string Message { get { return _message; } set { _message = value; } } public DerivedClass(string message) { Message = message; // Warning: Virtual member call in a constructor } public DerivedClass() : this("Default DerivedClass message") {} public override void PrintMessage() { Console.WriteLine("DerivedClass PrintMessage(): " + Message); } } I did find some other questions about this warning, but in those situations there is an actual call to a method. For instance, in this question, the answer by Matt Howels contains some sample code. I'll repeat it here for easy reference. class Parent { public Parent() { DoSomething(); } protected virtual void DoSomething() {}; } class Child : Parent { private string foo; public Child() { foo = "HELLO"; } protected override void DoSomething() { Console.WriteLine(foo.ToLower()); } } Matt doesn't describe on what error the warning would appear, but I'm assuming it will be on the call to DoSomething in the Parent constructor. In this example, I understand what is meant by a virtual member being called. The member call occurs in the base class, in which only a virtual method exists. In my situation however, I don't see why assigning a value to Message would be calling a virtual member. Both the call to and the implementation of the Message property are defined in the derived class. Although I can get rid of the error by making my Derived Class sealed, I would like to understand why this situation is resulting in the warning.

  • Performance problem Loading Dataset inside a virtual.

    - by ShaneH
    Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

  • VSC++, virtual method at bad adress, curious bug

    - by antoon.groenewoud
    Hello, This guy: virtual phTreeClass* GetTreeClass() const { return (phTreeClass*)m_entity_class; } When called, crashed the program with an access violation, even after a full recompile. All member functions and virtual member functions had correct memory adresses (I hovered mouse over the methods in debug mode), but this function had a bad memory adress: 0xfffffffc. Everything looked okay: the 'this' pointer, and everything works fine up until this function call. This function is also pretty old and I didn't change it for a long time. The problem just suddenly popped up after some work, which I commented all out to see what was doing it, without any success. So I removed the virtual, compiled, and it works fine. I add virtual, compiled, and it still works fine! I basically changed nothing, and remember that I did do a full recompile earlier, and still had the error back then. I wasn't able to reproduce the problem. But now it is back. I didn't change anything. Removing virtual fixes the problem. Sincerely, Antoon
