I used qemu sucesfully on F9 but I can't find it on F10. I can't create a virtual machine. I tried installing qemu from rpms that I found on their site without any luck. How can I create a virtual machine on F10?
View 2 RepliesI just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.
Here are some infos:
Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686
virt-manager-0.8.5-1.fc14.noarch
We have a virtual XP machine on our fedora 11 install. I want to drop fedora 11 down to init3 (since its a server anyway) and everyone is worried about the windows virtual machine dying. What would happen to my windows virtual machine if I drop the host server to init 3?
View 1 Replies View RelatedI have an F12 installation on which I have installed NoMachine's NX server. I can remote in nicely when needed (try to do as much as possible via SSH) while not having to boot into and stay on Gnome on the server and run VNC.I noted that when I try to start the Virtual Machine Manager from an NX session, I get an error that VMM is "unable to open a connection to the libvirt management daemon". libvirtd is running, however. And, when I startx on the server and try there, VMM works fine.Is this an inherent problem with the use of VMM, or something correctable?

I have 8 VMs on this virtual machine running different OS. Can VMs be moved/copied to another PC of similar hardware config running Fedora 12 (64bit) as host and KVM
If Yes, whether copying following files,
e.g. copying following files and paste them on the same /path/to/directory

I'm running Fedora 11 (2.6.30.10-105.2.4.fc11.i686.PAE) 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.
View 4 Replies View RelatedI have been unable to create any type of Windows VM in Xen. Every time it tells me that the processor(s) in the machine do not support full virtualization. After some research, I found several articles regarding the vmx setting in /proc/cpuinfo not showing up when the xen kernel is booted versus it showing up in the default kernel. Of course, I am not seeing the vmx extension in /proc/cpuinfo after I boot to the xen kernel. In the other posts where other people are in the same situation, the only resolution is to upgrade to the 2.6.16 xen kernel. I am already past that:
linux-vxke:~ # uname -r
2.6.31.8-0.1-xen
yet I am still unable to create any form of Windows VM. I have even seen that some people are able to create a partially virtualized Windows VM, and they report that the message is only a warning. However, I am unable to get past this message. I am running a Dell Optiplex 760 with an Intel Core 2 Duo E7300, and I have the VT-x setting enabled in the BIOS. Has anyone else seen this situation or have any thoughts on why this is happening?

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?

I'm working on a script. fter it has installed and removed packages, I need to configure a ton of settings. In GNOME, I understand that those settings are kept in "/home/user/.gconf". Can I create a virtual machine and configure the system through the GUI to my liking and then dump all of the settings, so that I can load them on another machine? Is it as simple as copying the directories?
View 2 Replies View RelatedI'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).
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command:

I've tried several times to create a Virtual Machine using KVM and installing Ubuntu Natty (using virt-manager).The problem is that each CD Install ISO I've downoaded appears to be corrupt... but it only appears to be! When I choose 'check cd for defects' before I am trying to install, every time a different error is reported... so I fear that the virtual CD drive does not work properly. (I am using IDE with the default settings...)Has anybody experienced similar problems? Can anyone point me to a hint or solution?btw... I've installed Windows 7 as a VM the same way. I did not experience any problems so far
View 2 Replies View RelatedI 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.

View 3 Replies View RelatedI needed to create a virtual host for a php project I'm working on. Rather than using command line and text editors, I installed webmin to accomplish this and hopefully perform other server configuration in the future. When I created the virtual host and tried applying the changes Apache wouldn't re-start, and still doesn't restart after complete re-boot. It's getting hung up at the end of apache2.conf, which is trying to include /etc/apache2/sites-enabled/000-default.
When I look at 000-default from a File Browser, it's a linked file to etc/apache2/sites-available/default I can open both the linked file and actual file in a text editor, and it looks fine. When I view the directory, /etc/apache2/sites-available from shell, the default file isn't visible. It seems this "invisibility" is probably related to the error, which is preventing start-up. Can anyone explain why the file would be visible from the Ubuntu File Browser GUI but not from the terminal, and how I can fix so apache can recognize this on start-up?
I believe I finally have a very secure config for apache2 that will only use SSL or port443.
Problem is how do I redirect all my users who dont type in https:// to the proper SSL port 443?
Do I have to create Virtual Servers? If so how?
Or is there a Redirect command?

Is there any open source virtual machine so i can study the source in order to create my own? i'm gonna write my own, so it doesNT matter if license does not allow further development of the code.
View 1 Replies View RelatedI've been reading up on clustering a bit and want to create simple 2 machine cluster of which the 2nd one will turn on and take over traffic at the previous machine's IP (I'm aware there will be a couple minutes of downtime while the failover server boots). I've looked into doing a simple DNS round robin, but I think both machines would need to be online all the time for this to function correctly. I've also looked into linux-HA and GlusterFS but both seem a little intense for the simple failover I'm trying to achieve. One catch if approaching with DNS round robin... the server that I want to setup with a failover also operates as a DNS server. Anyone know the simplest way to complete this? One idea I had (that seemed like a bit of manual work): Create script that runs every 60 secs through CRON on firewall (running pfsense) and have it check if master-server is up. If it's not, it will send a WOL signal to the slave, which has a mirrored image of the first. the problem I have with that is I will also need to create a script to keep both synced properly which seems almost impossible if one is shut down until failover (my thought was periodic rsyncs.) Perhaps creating a FS to direct all files to for the master/slave would be the only way around that.

View 8 Replies View RelatedI'm having some issues with a windows virtual machine. The system is Fedora 11 and the virtual machine is Windows 2008 Server. If I start the virtual machine from the virtual machine manager, it only has a single cpu despite my setting it to eight. If I start the machine from the command line, I can get four cpus but not eight. In both cases windows seem to display the eight cpus in the device manager (or whatever program it is). It has been suggest that windows was imaged on a four core machine before being loaded on the eight core machine and that something in windows is maxing at four cores. But that doesn't explain why the virtual machine manager can only start one cpu. I just played around on my home machine with a fedora 10 live cd and it recognized the two cores on that machine and used them from the virtual machine manager without problem. Also upped it to three cpus without problem.

I am experiencing a multicpre problem with fedora14 / kernel 2.6.35.6-45.fc14.x86_64 #1 SMP. (standard from the distro). The host has a total of 2 cores .yet a virtual machine started with 'smp 2' ( or xml : <vcpu>2</vcpu>) will not run on 2 pyhs cores . it will use just 1 core ('top' at the host shows 100%cpu while running an endless loop process on the VM) and libvirt 'virsh vcpuinfo <vm name>' shows only 1 physical cpu used (although 2 vcpus are used : 0, 1) The kernel seems to be an SMP one ( so says the uname -a . what does '#1 SMP' mean ?) . Am I missing something ? same XML on a DEBIAN machine will run the VM with 2 phys cores as should although the host there has 4 cores (>2)Should I recompile the kernel src with some addtional flag ?

I don't know how to load windows XP.
The vm1 virtual machine console is frozen with the message "Booting from hard drive." But I know it can't boot from hard drive because I haven't loaded windows XP yet. When I created the vm1 virtual machine I put the windows XP CD in the optical drive and directed the menu to the CD. I heard it running, but still the console is trying to boot from the hard drive. I never got to the point where it asked me any windows XP software loading questions.
