[ovirt-devel] trouble with already existing mac address in database

Hi,

jhernand was so kind to resolve this for me and asked
for a mail to devel, because some people might be interested in it.
so  here it is:

situation: you removed a vm somewhat dirty from ovirt by deleting
it in the database, now you want to reuse it's mac address, but ovirt
won't let you do it, because "Mac address is already in use."

At first I thought I had not deleted all entries regarding this
vm, but even when I did a dump of the whole engine db and grepped
for the mac it didn't yield any results, so the mac was not in the
db anymore, yet ovirt complained.

what helped, was a restart of the engine service, because ovirt
seems to cache some values in ram, like macs.

so in case you got trouble like this, just restart the service.

I wonder if it might be worth an RFE, so engine checks from
time to time if values in ram are also in the db and if not
cleans the ram?

thanks again to jhernand for the (somewhat obvious) solution!

site note:
ovirt-engine is a really fast restarting service, pretty cool.
