Hi, I have the following setup: Host: Ubuntu 10.04 Guest: Windows 2008 R2 Kernel: 2.6.32-40-generic virt-inst: 0.500.1-2ubuntu6.2 qemu-kvm: 0.12.3+noroms-0ubuntu9.18 All is working, however I would now like to share a given directory on the host with the guest. Using the "virsh edit" command I have prepared the following XML configuration snippet: <filesystem

Hello, I am using libvirt on Ubuntu 10.04 Server and the following versions of these packages: libvirt-bin, libvirt0, python-libvirt - 0.7.5-5ubuntu27.22 qemu-kvm 0.12.3+noroms-0ubuntu9.18 Recently, when restarting a VM (either by issuing "sudo reboot" on a Linux guest or choosing "Restart" from the Start Menu on a Windows guest) the VM shuts down and remains off rather

Hello libvirt experts, I use libvirt (0.7.5-5ubuntu27.7) with KVM / qemu (0.12.3+noroms-0ubuntu9.2). Some machines use raw images but same use Virtualbox images (.vdi). Since last Ubuntu 10.04 LTS update I can not start the vdi-images. The "driver name= type=" option was new. <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file'

Dear all, I'm looking for a bit of help with a problematic VM. We have an hypervisor which has 4 eth ports. 3 are already used, and I wanted to pass the 4th one directly to a VM (which is fully working without it). So, I modified the XML accordingly (which matches our hardware), adding: <hostdev mode='subsystem' type='pci' managed='yes'> <source>

Hi, I wanted to migrate a mailserver from cyrus to dovecot. The new setup was using postfixadmin let the domain admins configure the hostet domains. To view the used quota in postfixadmin the usage of the quota dict backend is required. I have configured it according to the wiki but everytime I connect I get a sucessfully login and then every next command hangs. It seems to me, that the dict

I am running Ubuntu 14.04.4 LTS ?Trusty? and "postconf -d | grep mail_version? gives me ?mail_version = 2.11.0?, with Dovecot 2.2.9 I have installed Sentora (http://sentora.org) which sets most of the configuration up for Postfix up, I have made some changes to allow me to use certificates for IMAP and SMTP SSL (https://skippy.org.uk/lets-encrypt-postfix-and-dovecot/), My Postfix main

My server and client are running Ubuntu Lucid, libvirt-bin 0.7.5-5ubuntu27, qemu-kvm-0.12.3+noroms-0ubuntu9 and I'm using virt-viewer-0.0.3-6ubuntu7.xul19 or virt-manager-0.8.2-2ubuntu8 to connect. I configured SASL2 to use GSSAPI for libvirt following the instructions in the libvirt docs, created a keytab with libvirt/my.fully.qualified.domain at MY-REALM.COM (has a dash fwiw) and pointed

I've been using libguestfs-1.18.9 but decided to "upgrade" to 1.19.60. Using Ubuntu 12.04 with the older version installed via source. So I went through the same process with the new version of guestfs sources and got the following errors on 'make install': make[2]: Nothing to be done for `install-exec-am'. make install-data-hook make[3]: Entering directory

my goal for testing/simulations is to be able to run a vm on my desktop and within that vm run linux containers currently I can start an ubuntu trusty vm using libvirt as my broker to qemu or qemu-system-x86_64 directly and start a saucy-based lxc using lxc-tools. I invoke lxc-start -n name -f configfile and within a few seconds I'm logged into my saucy based lxc. I can't start the lxc

Hello, Been a long time since I broke out your libguestfs tools. Current employer has some old machines they want to virtualize before they croak. I was able to virtualize a Win2000 box but when I tried the same with a Windows 95 machine the call to guestfs_list_partitions returned null. I did make that image with a different tool (my linux box wasn't available so I wound up using Macrium

Hi all, We've got a department that has 5 phones using a * 1.0.9 box. They need to have an extension that rings all 5 phones at the same time. Getting all of the phones to ring isn't a problem, but they are running into a problem with the phones ringing in their ears when they are already on a call. Example: Caller one calls the queue, all of the phones rings, and employee one

When I start using "<target dev='hda' bus='ide'/>" in HDD config, it works. When I start using "<target dev='vda'

Hi. I was cloning a domain and now I can't boot the original nor the clone domain. Currently when I start one of those domains I can see only a blank screen. I am not sure what went wrong cloning. I was trying to use kpart to mount the new image and change info in the filesystem like hostname, ip and so. Anyway when I start the new or old domain: # virsh start --console thedomain

Hi Guys, I'm currently learning KVM and have set up an Ubuntu 12.04.2 VM running KVM.
