I'm playing with VMWare ESX 4.0 and I decided to try driving it from
libvirt [git version]. Here are some random questions and issues I
encountered, in no particular order.
Listing domains works fine, but:
(a) I have to specify ?no_verify=1 to get it to ignore the lack of
valid https certificate. Is there some documentation on how to set up
certificates correctly? [vSphere gives exactly the same error]
(b) I have to type the root password (of the ESX server) each time.
Can I avoid that?
$ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' list --all
Enter username for 192.168.2.121 [root]:
Enter root password for 192.168.2.121:
Id Name State
----------------------------------
- TestLinux shut off
- TestWin shut off
(c) Starting domains doesn't seem to work, and the error message is
obscure:
$ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' start TestLinux
Enter username for 192.168.2.121 [root]:
Enter root password for 192.168.2.121:
error: Failed to start domain TestLinux
error: internal error HTTP response code 500 for call to 'PowerOnVM_Task'. Fault: ServerFaultCode - The operation is not allowed in the current state.
Is this to do with the "ask questions" API that was discussed on this
list before? Specifying auto_answer=0 or auto_answer=1 didn't make
any difference.
(d) dumpxml XML output looks very good, and consistent with the other
drivers. However it produces an odd <source file> attribute:
<disk type='file' device='disk'>
<driver name='lsilogic'/>
<source file='[Storage1] TestLinux/TestLinux.vmdk'/>
<target dev='sda' bus='scsi'/>
</disk>
<disk type='file' device='cdrom'>
<source file='[Storage1] Fedora-12-x86_64-Live.iso'/>
<target dev='hdc' bus='ide'/>
</disk>
(e) pool-list, net-list are not supported by the driver.
That's a particular problem for me because I was really hoping to use
the storage APIs from libvirt to access the VMDK files that contain
domains (eg. [Storage1] TestLinux/TestLinux.vmdk in the example
above). Is support for storage (particularly) and/or networks on the
horizon for this driver?
