Hello, i want to start a guest OS in the server, and use spice to achieve graphical interaction with the guest OS. But when i config the XML file, i was confuse by spice . The graphic node is : <graphics type='spice' port='5990' ><listen type='address' address='127.0.0.1'/></graphics> but is has such error as below : libvir: QEMU error : internal

Hey When I want to take a snapshot for a Domain by using virDomainSnapshotCreateXML. The Error as below happen: libvir: QEMU error : Requested operation is not valid: Disk '/var/lib/libvirt/images/fedora-qcow.qcow2' does not support snapshotting The snapshot Configuration is : <domainsnapshot> <description>Snapshot of OS install and updates</description>

Hi All, I find that I am able to attach a disk device do a Xen domain, using virDomainAttachDevice(), running as a non-root user, but I am unable to use virDomainDetachDevice() - it results in an "unknown failure". Using "virsh [attach|detach]-device" exhibits this behviour. $ virsh attach-device domu1 attach.xml Device attached successfully $ virsh detach-device domu1

Hi buddy, I wanna to monitor a domain's life cycle event, so i register a event an a virConnectDomainEventCallback, the code segment is as below: ------------------------ int DomainEventCallback(virConnectPtr conn, virDomainPtr dom, int event, int detail, void * opaque){ /*My code */ ....... } int main(){ /* .....*/ virDomainPtr dom =

Hi, when I try to use such API: virDomainPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virDomainPtr> virDomainMigrate (virDomainPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virDomainPtr> domain, virConnectPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virConnectPtr> dconn, unsigned long flags, const char * dname, const char * uri,

Hi All, I had configured a samba server running on linux OS (Redhat )and till this days it was working fine with quotas set on the users.. I restarted nmbd and smbd service .. but still the below mentioned persists..

Hi, This patch makes it possible for Qemu to use the SDL library, to conveniently replace VNC, which has horrible mouse support. It also adds a IOEMU_CONFIGURE_OPTIONS option in tools/Makefile, so that later on, we can call: $(MAKE_CLEAN) -C $(DIR)/tools $(CONFIG) IOEMU_CONFIGURE_OPTIONS="--audio-drv-list=\"pa oss alsa sdl esd\" --audio-card-list=\"ac97 es1370 sb16 cs4231a

Buddy, I am a noob in libvirt develop. When I want to create a domain by using virDomainDefineXML and displays a window on the host desktop. But when I add the line " <graphics type='sdl' display=':0.0'/>" into the config xml file, the error as below will happen. libvir: QEMU error : internal error process exited while connecting to monitor: Could not initialize

Is there any way to get virsh / libvirt to create a domain such that I can later connect to it via QMP (without hacking the code)? The command line that libvirt creates for my current setup looks like this: /usr/local/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name winxpsp2 -uuid ab244939-c804-1aff-68b6-9324f174c3c8 -nodefconfig -nodefaults

Good day to all. i have problems with cdrom hot adding code. currently i using virDomainAttachDevice with type=file, device=cdrom, dev=hdc, this code works for machine with one ide hdd and one ide cdrom, but this not work for machine with only one ide hdd, and i looking for solution to hot add cdrom to machine independent of existing devices or i need way to determinate which target device

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

Hi,all,i build qemu-kvm1.0.93 from source code on centos6.2 , # qemu-system-x86_64 --version QEMU emulator version 1.0.93 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard and the guestfish's version: # guestfish --version guestfish 1.7.17 but when i use the guestfish command to upload a file to a vm,it does not work , # guestfish --rw -i -d centosvm upload /test/ifcfg-eth0_centos

Ok, is this possible: I want to have a 128k and a 24k stream of a particualr audio program, plugged into the line in of my Ensoniq AudioPCI 128 (es1370 chipset) Is there any way to do this with just one soundcard, or do I need two?

CentOS-6.2 We have a dedicated CentOS-5.7 host used for fax reception and transmission that we wish to move to a CentOS-6.2 virtual guest instance. The CentOS-6.2 virtual host has a 4-port serial card installed. lspci -v tshows this this: 03:00.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad 16950 UART) function 0 (Uart) (prog-if 06 [16950]) Subsystem: Oxford

libguestfs recently added support for virtio-scsi and libvirt, and when these are both available this lets us relatively easily add hotplugging of drives. This email is about how we would present that through the libguestfs API. (a) The current API Currently you have to add drive(s) via guestfs_add_drive* and then call guestfs_launch, ie. your program must look something like this: guestfs_h

Hi I tried to use virsh blkstat to get information of a block, but it returns an error message as shown below This function works fine in KVM, but fail in XEN. I tried XEN 3.4.3 ,4.0.0 and 4.0.1 with libvirt 0.7.1 from fedora yum server and 0.8.1 from libvirt . All of them are fail to get the block status. The following is the config file and error message of virsh domblkstat. Any one

Hi all, I've disabled cgroups v1 on my system with the kernel boot option "systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging fails to work, seemingly due to a permissions problem with BPF. Please note that the technique I'm going to describe worked just fine for hotplugging USB devices to running domains until this change. Attaching / detaching USB devices

Hi, Is there an equivalent of "virsh attach-device -live -persistent " within libvirt API : virDomainAttachDevice() or virDomainAttachDeviceFlags() or ??? Thanks for help. Regards, J.P.
