Hi, Dear. I have two questions ask for help: my virt-manager and libvirt version is : linux-vaan:~ # rpm -q libvirt libvirt-0.8.5-1.2.i586 linux-vaan:~ # uname -a Linux linux-vaan 2.6.34-12-desktop #1 SMP PREEMPT 2010-06-29 02:39:08 +0200 i686 i386 GNU/Linux linux-vaan:~ # rpm -q virt-manager virt-manager-0.8.5-3.1.i586 linux-vaan:~ # cat /etc/SuSE-release openSUSE 11.3 (i586) VERSION = 11.3

virsh # version Compiled against library: libvir 0.8.5 Using library: libvir 0.8.5 Using API: ESX 0.8.5 Running hypervisor: ESX 4.1.0

question 1 : When I try to create a vmware esxi domain from virsh like this :        create --file /work/dom1.x  there is a  error message :        error: Failed to create domain from /work/dom1.xml        error: this function is not supported by the connection driver: virDomainCreateXML it seems dosen't support create esxi domain, but the http://libvirt.org/hvsupport.html show that is supported after ≥ 0.7.0

virDomainCreateXML and virDomainCreate are different. virDomainCreateXML creates a new transient domain and starts it, virDomainCreate starts a persistent domain that has been created using virDomainDefineXML before. A transient domain will automatically go away when it is stopped. A persistent domain won't and has a persistent config stored to disk. ESX(i) doesn't have this transient semantic for it's domains, therefore libvirt can't support virDomainCreateXML for it. In order to create a new ESX(i) domain you need to define it using virDomainDefineXML. In virsh use 'define /work/dom1.x' instead of 'create --file /work/dom1.x' to create a new domain, then use 'start dom1' to start it.

or create via virt-install

          linux-vaan:~ # virt-install --connect=esx://root@192.168.8.162/?no_verify=1 -n rhel5 -r 512 --vcpus=1 --nodisks bridge=vmk0 --network bridge=vmk0 --pxe

          Enter root's password for 192.168.8.162:

          Starting install...

          ERROR    this function is not supported by the connection driver: virDomainCreateXML

how to  fix it ?

Unfortunately virt-install doesn't work for ESX(i) yet. One reason is that it uses virDomainCreateXML, but there are some other things that need to be implemented or solved before virt-install will be able to install an ESX(i) guest.

dom1.xml <domain type='vmware'>   <name>dom1</name>   <memory>524288</memory>   <currentMemory>524288</currentMemory>   <vcpu>1</vcpu>   <os>     <type arch='i686'>hvm</type>   </os>   <clock offset='utc'/>   <on_poweroff>destroy</on_poweroff>   <on_reboot>restart</on_reboot>   <on_crash>destroy</on_crash>   <devices>     <disk type='file' device='disk'>       <source file='[datastore1] rhel5/rhel5_2.vmdk'/>       <target dev='sda' bus='scsi'/>       <address type='drive' controller='0' bus='0' unit='0'/>     </disk>     <controller type='scsi' index='0' model='lsilogic'/>     <interface type='bridge'>       <mac address='00:0c:29:51:f1:1c'/>       <source bridge='VM Network'/>     </interface>   </devices> </domain>

This domain config looks good and should work assuming '[datastore1] rhel5/rhel5_2.vmdk' exists. You can use virsh vol-create to create it if it doesn't.

question 2: vol-clone failed

virsh # vol-clone --pool datastore1 rhel5/rhel5.vmdk rhel5/rhel5_2.vmdk

error: Failed to clone vol from rhel5/rhel5.vmdk

error: this function is not supported by the connection driver: virStorageVolCreateXMLFrom

virStorageVolCreateXMLFrom wasn't implemented for ESX(i) until now :) I just implemented it and it'll probably be part of libvirt 0.8.7. Matthias
