Ubuntu Servers :: Image-virtual: For Host Machine Or Guest OS?

Dec 2, 2010

I couldn't find a clear answer to this, but is the linux-image-virtual package for host machines that will contain VMs, or a VM-oriented kernel for guest OS (ubuntu)? I have some guest VMs running on Microsoft's Hyper-V, and was looking for some further optimizations.

Ubuntu :: Migrating Virtual Guest To Native Host?

Nov 5, 2010

Migrating Virtual Guest to Native Host

I have been using ubuntu server and desktop on virtual box for a while now. I have come to enjoy it more than being in Windows. I would like to install it natively. I am wondering. is there any way I can take my virtual machine and apply what I have done there to a new ubuntu install?

I have a ntfs hard disk, will ubuntu resize that for me at install?

Any good apps for backing up all my my firefox data and then applying that to my firefox in ubuntu?

I need to keep windows for some stuff for work, and for some games I like.

Fedora :: Installing Virtual Guest On FC13 Host

Jun 26, 2010

How do I make a Guest img on hard drive and install Guest on a FC13 host? Is there a set of instruction for doing it on a FC13 host? I went to this website for the FC13 KVM instructions, but near the bottom of page 1 he starts off with making a Guest, Debian Lenny, on ubuntu. Chapter 4 Creating A Debian Lenny Guest (Image-Based).

He has got me so confused at this point on whether he is installing a Fedora or Ubuntu Guest. On that 1st page all steps for making a Host is completed on my Host computer. [URL]. I have got the Windows XP disk in the CD ROM ready to go. If you do a Google search on KVM. Any prior instructions just does not work for Fedora 13

Ubuntu Networking :: Server + KVM. Guest Os Can Reach Wan But Host Machine Cannot?

Oct 13, 2010

I've set up ubuntu server 10.04 x64 with kvm and bridged networking and installed win server 2008 as a guest os. The guest os has full access to the network including lan/wan but the host os can only reach my lan and not the wan. This is true even when the guest machine is powered off?I have to admit that my knowledge of networking, particularly with respect to linux is very flakey but surely if the guest has internet access this should also apply to the host? My only suggestion is an issue with mac addresses but i don't know where to start. Has anybody ran into this problem before?

Ubuntu Servers :: KVM On 9.10 Host And Guest - Internet Disconnects For Some Seconds

Feb 25, 2010

I run KVM on 9.10 host and guest 9.10. Both are x64. When I halt the guest os:
My host OS looses its connection with internet for 10-15 seconds and then it comes back on. Probably something goes wrong with default gateway, as it looses only external network (I still can reach it on my internal network). I've googled a lot, but cant find anything about that. I use bridged network.

CentOS 5 :: Create Virtual Machine From Existing Image?

Jan 3, 2011

I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

Networking :: Isolating A VMware Virtual Machine From It's Host But Still Alowing Internet Access

Oct 31, 2009

I have a WindowsXP virtual machine which I need to isolate from the host machine completely (have the host act as a bridge but not be visible on the IP layer at all.) It still needs to have Internet access. Obviously it has to be able to contact the router but I would like to be able to block port 80 (or even just block all SYN packets addressed to the router.) I also want to allow port forwarding from the router to the virtual machine. I can use basic iptables but this is way beyond me.

The host OS is probably going to be Debian Lenny but this is not built yet so if someone can recommend a different distro which is as lightweight as possible but will support VMWare, iptables and tcpdump then that would be great. I was thinking of Slackware but I have not used it in ages and from what I can remember their is no real package management.

CentOS 5 Server :: Create Qcow2 Image In 5.5 Virtual Machine Manager?

May 18, 2010

I'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.

Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?

I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?

When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).

Fedora :: Use Existing WIndows 7 As Guest Virtual Machine In Fedora 12

Apr 5, 2010

My company's default OS is Windows 7. I convinced my manager so that I could use Fedora 12, since I am mostly familiar with development environment in Fedora. However there are a few things I need in Windows 7, and I want to stop going back and forth in two OS'es in dual boot-up setting.

I've searched online for easy way to use the existing Windows 7 as guest virtual machine. I first tried VMware's Vcenter Converter Standalone in Windows 7, but it failed with some error code, and searching the particular error code didn't turn up any solution. I also tried to use Sun's VirtualBox, but I get segmentation fault error in Fedora. I tried to see if VMware server has a tool, but installation exists with an error, and searching the web for the error code didn't turn up anything either.... I wonder if I am having this much difficulties because I am using x86_64 version of OS'es.

Anyhow, if anyone has done it successfully - using existing Windows 7 as guest virtual machine in x86_64 version of Fedora 12.
