These are the messages that I get when trying to attach a virtio disk to or perform a shutdown of the problem vm guest. Add hardware This device could not be attached to the running machine. Would you like to make the device available after the next guest shutdown? Requested operation is not valid: cannot do live update a device on inactive domain Traceback (most recent call last): File

CentOS-6.6 virt-manager 0.9.0 I have cloned a template server with a 32GB virtio HDD already defined and am attempting to add additional virtio disks. The basic cloned system boots without error. If I create a virtio disk with 32000/32000 megabytes I can add it and the system reboots; providing that I do not first create a partition: fdisk -l /dev/vg_vhost03/lv_vm_inet11.harte-lyne.ca_03

CentOS-5.4 i86_64 I have a calculator applet on my desktop (superbcalc.jar). When I double click on it I get no response. If I right click and select open with java I get no response. If I open a terminal window and cd to Desktop and type java -jar superbcalc.jar then the applet opens. Does anyone have any idea why I am seeing this behaviour? There are no messages in the syslog file relating

I am in the middle of a rather confusing situation. At the moment I am unable to shutdown a KVM guest machine. Nor am I presently able to open a virt-manager session on the host. I am not exactly sure what has happened but the problem with the vm guest is that issuing a "virsh shutdown 1" from the root console has no effect. # virsh list Id Name State

What is the correct combination of packages to configure and manage VMs via virt-manager undet CentOS-5.4? If I use qemu then while virt-manager works I obtain SELinux alerts with respect to the real-time clock. If instead of qemu I use kvm-qemu-img then virt-manager simply does not work. It starts but it does not find any form of qemu and the selection boxes are all greyed out. Further, do I

Need to start a virtual machine but missing nic is preventing this: I have need to recover some data from a guest on host which has been shutddown for some time. The host had one of it nic removed at some point. It is not likely to be replaced either. When I try to start the guest in question I get this: error: Failed to start domain inet09.harte-lyne.ca error: Cannot get interface MTU on

CentOS-6.0 I created an lv (120 Gb) to hold the image of a KVM guest instance. I mounted this at /var/lib/libvirt/images/lv_guest01. When I do a df I see the lv is mounted at the desired location. When I run the virtual machine manager from the desktop I am given the option to install the image into the root directory tree or to browse for an alternative location. When I browse to the mount

Is it possible to use this exploit against a kvm guest to read memory used by the host? In other words: if an exploitable service, say httpd with mod_ssl, is running in guest system 'vm1' hosted on system 'virthost' then what implications does that have with respect to guests vm2 and vm3 and to virthost itself? -- *** E-Mail is NOT a SECURE channel *** James

i86_64 CentOS-6.5 I have installed a Windows instance as a kvm guest on a host running CentOS-6.5. I can access the desktop through the virt-manager console and everythign seems to work, although the mouse cursor seems to get lost from time to time. The virt-manager console display supports various resolutions but when I re-size the desktop display remains essentially a square inside a letter

I have a CentOS-6 guest VM configured on a CentOS-6 host. If I run virt-manager then I can start the guest VM but once it is running I cannot get a shutdown command to have effect. To shutdown the running guest I either must select Force Off from the Shut Down menu or open the guest console and issue shutdown from the command line. Is there some setting that is required to have Shut Down have

I still get the same errors after adding my user id to /etc/at.allow. I tested whether job control was enabled by moving top into the background using ctrl-z and fg to return and that worked.

I have a kvm guest running MS-WinV7 on a CentOS-6.5 host. The WinV7 guest was installed from a CD. It installed correctly and was updated and added to an MS Active Domain without difficulty. I was able to do work on it through the virt-manager console and I was able to shut the system down from the console without problem. I cannot get it to restart however. virsh start

To get the server working again I reinstalled the previous version of openssh and the service came up without complaint. cd /tmp; rpm -i openssh-4.3p2-41.el5.i386.rpm --force --nodeps cd /tmp; rpm -iv openssh-server-4.3p2-41.el5.i386.rpm --force --nodeps cd /tmp; rpm -iv openssh-clients-4.3p2-41.el5.i386.rpm --force --nodeps cd /tmp; rpm -iv openssh-askpass-4.3p2-41.el5.i386.rpm --force
