Configurations read only

[SergeyDjam]

Hello. Actual version 0.43.70.2. Don't write configuration.

1. I open virtual machine edit
2. I make changes
3. I save and close
4. I open editing again and I see that nothing changed

what? what this fix?

at first, need to see Log about error edit action. usually libvirt send error about occured errors. maybe configuration is not correct.

[SergeyDjam]

No errors. Virt-manager edit this vm

[F1ash]

Which parameter not changing? What is state of VM (running, shutoff, etc.)?

[SergeyDjam]

All parameters don't change. Status VM off, no hibernate

[F1ash]

I'm fixed send error messages at edit VM configuration in new version. If you can build it and run, then you can see occured errors. I can't reproduce this bug. But if you make some changes with changed name or UUID, then you get error same:
✻ 11:34:28 Connection '{Local1_QEMU}':
ACTION:
VirtError(9) : ошибка операции: домену «QEmu-F20-KDE-min1» уже присвоен UUID e63451fc-3fe5-4e1b-b73f-7e930d4506e3

or same:
✻ 11:36:27 Connection '{Local1_QEMU}':
ACTION:
VirtError(9) : ошибка операции: домен «QEmu-F20-KDE-min1» уже существует (UUID: e63451fc-3fe5-4e1b-b73f-7e930d4506e3)

[SergeyDjam]

Problem not in local placement of the virtual machines, and it is exceptional on remote servers

Важно, что серверы под управлением CentOS 6.6 (RELS 6.6)

[F1ash]

Strangly... Because, as i can see, API virDomainDefineXML not changed since 0.2.0 libvirt version.

[SergeyDjam]

Version 0.43.72. This problem too.

[F1ash]

Any errors in Log after probe to edit VM config?

[SergeyDjam]

Nothing shows errors. Where to me to look at these errors?

[F1ash]

Enable Log if disabled.
Show Log about messages with your connection name.

P.S. если удобней общаться на русском, то я обычно сижу на fedora@conference.jabber.ru, там можно пообщаться в личке более детально.
