...to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of virtual machines. I can backup the filesystems of a virtual machine in this way: # losetup /dev/loop1 /dev/virtualmachines/windows7-x64 virtualmachines is the name of my volume group. windows7-x64 is the logical volume. # kpartx -av /dev/loop1 Then I would see the partitions of the virtual machine within a logical volume, like so: /dev/mapper/loop1p1 /dev/mapper/loop1p2 /dev/mapper/loop1p3 Now that I can access t...

Hi Team, I am using libvirt module to retrieve configuration of the virtual machines, Can you please tell me how to retrieve the disk space of the Virtual machines. In my KVM hyper i am running two virtual machines. Regards Manzoor

Hi, I can authenticate with the smbd from macos 10.12 using smb 3.6.25 inside a vm running on the same machine. smbclient -L 192.168.0.87 -U username --signing=off works. But when using the same command from a different PC i get NT_STATUS_LOGON_FAILURE. It is the same client setup. Any clues? Markus  <div style=\"border:0;border-bottom:1px solid black;width:100%;\">

HI I tried to follow the procedure at http://vmkit.llvm.org/get_started.html . Builds of LLVM and classpath went fine (after fixing a few dependency problems). After compiling a simple HelloWorld with javac I got ../vmkit/Debug/bin/jnjvm HelloWorld hang for a while and then spits out a terminate called without an active exception Abort I also tried to compile on a machine with gcc 4.1 and

Hi, Is there a bug under cron on CentOS 5.2 x86_64 ? kernel 2.6.18-92 Something is strange on my system. I have a simple shell script to run on many computers .

Hi unfortunately VirtualBox does not work yet in a Solaris Dom0: I installed VirtualBox beta and it runs fine on bare metal. Unfortunately the necessary driver does not load automatically in a xVM Dom0. It can be loaded manually but it looks like it does not work in a Dom0: bash-3.2# modinfo | grep vbox # this is a one time task: bash-3.2# cp /platform/i86pc/kernel/drv/amd64/vboxdrv

Hi virt, im stumped... any help would be appreciated. I normally create my VMs like this: base="http://mirror.pnl.gov/fedora/linux/releases/20/Fedora/x86_64/os/" sudo virt-install --hvm --name $vm_name$i --ram 4000 \ --disk path=/VirtualMachines/$vm_name$i,size=30 \ --location $base -x "ks=http://xxx.os21.ks$kx" HOWEVER... I'm finding that my VMs dont boot after i restart the Host. My question is: Where is virt-install writing the boot disk to? I get a error message that the "boot failed" because the hard dis...

Hi All, Thanks Nicolas for pointing out that I needed --enable-targets=x86,cpp for my llvm config to get vmkit to build. The process gets a lot farther but fails in different places depending upon the vmkit config (Can you please see the three case below?). My machine is a intel core i7 running ubuntu karmic and gcc 4.4.1. What arch/OS/distro/gcc do you all have VMKit working on? thanks for

I've begun working on a syslinux project with a portable usb drive. Up to this point I was a pxelinux.0 user only. My virtualmachine system (Oracle VirtualBox) can netboot so testing config file changes was no big deal. VBox is currently unable to boot from a usb drive despite documentation that says it is possible. Is there a windows based tool that can scan and test a syslinux

Hi, The VMKit framework has been updated to be more generic. The getVirtualTable method is not exposed anymore since this method suppose that your object layout contains a virtual table. Now you have new methods to get / set objects type which are virtual methods inherited by the vmkit::VirtualMachine class. Thus you can still keep your object identity as virtual tables, but now the

Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI.

It is a maildir system. ( postfix + dovecot ) Now that...

All, I have successfully installed CentOS 7 on a PV environment, and have been trying to see if I can can get a CentOS 8 install running. Hardware does not support virtualization extensions, hence the PV environment and I cant do HVM for the install then migrate. My understanding is that PV support is in the kernel, and that the distro of Linux shouldn't technically matter. But currently
