[libvirt] can't get right capabilities
Hi, I am trying to use x86 machine to create VMs. But one error occurs. [root@mcd kvm-test]# virsh create test.xml error: Failed to create domain from test.xml error: unknown OS type hvm My xml file is as the following: <domain type='kvm'> <name>test</name> <memory>524288</memory> <memorybacking> <hugepages/> </memorybacking> <vcpu>2</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> </os> <features> <acpi/> </features> <clock offset='utc'/> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk' > <driver name='qemu' type='raw'/> <source file='/home/zhlbj/kvm-test/disk1'/> <target dev='sda' bus='scsi'/> </disk> <interface type='bridge'> <source bridge='virbr0'/> <mac address='52:54:00:19:bc:0c'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <memballoon model="none"/> </devices> </domain> I check kvm module, it is available.

It may be you're missing some rpm packages installation such as yajl(yajl-devel) or usbredir.

Maybe you are right.

I have installed rpm packages, error still occurs. On the stdout, it still reports: error: Failed to create domain from test.xml error: unknown OS type hvm

Hi,
I am trying to use x86 machine to create VMs. But one error occurs.
[root@mcd kvm-test]# virsh create test.xml error: Failed to create domain from test.xml error: unknown OS type hvm
Did you restart libvirtd after modprobing the kvm modules? Does anything appear in dmesg regarding kvm? Are you running any other virtualization solution besides kvm when you are trying to do that ?
Yes, I restart libvirtd. Actually, I can use qemu command line to create a VM. On my machine, there is only kvm installed, no other virtualization solution.
