If i not used virtualization then i have faced one problem that contents are not scrolled up/down during the drag operation. Can any on...
Afternoon all. I'm running a VMWare environment using VSphere etc. I've got a datacentre (vDataCentre1) with a number of clusters (vClusterA, vClusterB, vClusterC). Within each cluster there are a number of physical machines (vClusterA: pMachine1, pMachine2). I've been asked to set up another virtualised environment using the same serve...
i want to create a virtual monitor. The way this would work is that the virtual monitor would appear in a window on my desktop. As far as Windows knows it is just another monitor. It occurs to me that it would, as a practical matter, have to be done as video card driver (i.e. rather than the video going out a wire to an LCD panel, it wo...
I am setting up private cloud for some experiments using xen as the hosting system. But I am faced with a problem for which I can't seem to get solutions. I have to do some kind of automatic provisioning of VMs given the server load. Eg: if server of type A gets to lets say 60% load the cloud should spawn off another vm instance of the ...
I've got application A which runs application B as a console app. I'd like to write unit tests as part of application A which validate the input to/output from application B, but application B uses hard coded paths to look for some of its inputs. I'd like to be able to run the application, but intercept the call to read from c:\whereve...
Hello guys, I am writing a VMM for intel x86 architecture. Most of the code contains x86 platform specific assembly and c code. Can some one help me how to debug the assembly code please including hardware data structures. ...
Hello, i have a DataGrid. And a bind a List<> to it and add at runtime in the code a few columns. After adding this columns the vertical scrolling isn't very good. The added columns in code are dynamic created, i think between 10 - 50. And there are about 140 rows. How can i fix it? I read something about ui virtualization, but i dont ...
Hi. I am using VirtualBox in Ubuntu with WindowsXP as the guest OS. In Ubuntu I have a PHP/MySQL server running as localhost and with the VM network set to bridged I am able to connect to localhost from the VM. However, I would like to limit the VM Guest to be able to continue connecting to localhost but NOT be able to connect to the ...
How can I simulate that I plugged an ethernet cable between 2 virtual machines with VirtualBox 3.2.10? Like that: 10.1.0.1 o===========o 10.1.0.2 thank you in advance Daniel ...
With a large set of tables in a SQL database, I've implemented the DataGridVirtualizingCollectionView to 'lazy load' where needed into the WPF front end using XCeeds DataGrid for WPF. This works quite well, but I notice that this class doesn't implement any kind of filtering mechanism. Looking at the documentation here it appears that t...
Virtualized Layouts are nice, but I find that they often feel a bit "chunky" due to the "tightness" of the virtual range. This could be improved by increasing the range - one or two steps ahead (and behind) would often be enough to improve the "responsiveness" of the list, especially when external resources (like images) need to be loade...
Hi, Here at work, we use a virtual infrastructure. We use virt-manager a lot, but I'm on a Mac and can't get it to work. Is there a way to make it work or an alternative ? Thanks, ...
Hi, I was sitting in a presentation where i was told it is ok to have a physical box (virtualized into two) where one resides in the DMZ zone and the other resides in the secured zone. I found that such an approach smells bad. Is there any production environment that uses such an approach. I don't have a lot of experience in this spac...
Hi, We're running a x86 Windows 7 Host with another x86 Windows 7 guest OS through Windows Virutal PC. The host machine is configured with 2 network cards - one for the host, one for the guest. However, though we can access the guest on the network, it will NOT connect to the internet. There are some special considerations on the netw...

The virtual machine tips me it only detected an i686 CPU. Is there any link between the...
I just need to install Windows 2008 64Bit on a virtual machine. How to??? Do I need a special type of processor? Do I need a "special" virtualization tool? Actually installation fails on startup with the message that the CPU is not able to handle a 64Bit system. host system: Windows 7 64Bit CPU: Pentium D (seems to be Smithfield 805) ...
Hi, I have a java application (a genetic algorithm, to be precise) that periodically starts a native process (the fitness function), waits for it to complete and reads the file it outputs. However, the native process can only be run once, because it reads from a conf file and binds a few sockets. Is there a way to virtualize the native p...
I inherited a xen server that is setup to have all the VM images hosted on an iSCSI mounted NAS array. We been experiencing a random (about every 2-3 days) issue where xen would crash all the VMs, leaving nothing but the Domain0 running. What appears to be happening is something causes the iSCI mount to hiccup. Running "vgchange -a y"...
I want to use the hypercall of kvm to communicate (just send strings, it is uni-directional) between the guest and vmm instead of creating a network channel between the guest os and host. I have only found the file arch/x86/include/asm/kvm_para.h in linux kernel? Is it similar to the system call of linux? How can I call these functions ...
When automating some virtual machines with vmrun I am encountering the issue with not being able to bypass the Guest OS ctrl+alt+del login screen. For example vmrun.exe -gu user -gp pass -T server -h my.server.local:443/sdk -u admin -p pass runProgramInGuest "[datastore] path-to-VMX" iexplore will not proceed. Without me manually goin...
