Any ideas what this may be and what should be done? It does seem to only occur on the machines that have higher network load than the others. 2) We did a pilot project of about 8 VM's (the above mentioned environment) and all went well. Now that we've moved it into production with many more VM's, I'm wondering about recommended tuning. I seem to recall from watching this list that there are a few sysctl's and the like that are highly recommended, I think they had to do with network settings and turning off "offloading" or somesuch. Does anyone have a quick & dirty list of "here's the first things you should always change" with regards to FreeBSD HVM (pvm drivers) under XenServer? 3) When migrating bare-metal non-VM FreeBSD machines (primarily webservers and mailservers) to the above Xenserver environment, we have always just created VM's from an ISO, installed apache, sendmail, etc. and then migrated the websites, mailboxes, etc. manually "across the wire" from the non-VM machines to the replacement VM's. Xenconvert does not seem to support FreeBSD/gpart/ufs. Does anyone know of a way (software or procedure) to take a bare-metal FreeBSD 9.1 install and turn it into a VDI or OVF/OVA that can be imported to Xenserver? Thanks in advance for any tips, pointers, or insight!
