comment What services does hosts.allow NOT affect?
ssh. mysqld. apache2. I could just go get a list of all the services running on a system, but wouldn't it be easier to help me LEARN how to make the determination myself? I don't actually come here for easy answers, but to learn how to get the answer myself. If the howtos on hosts.allow had such information, I wouldn't have had to ask the question.

While there might be too many to name them all, can you name a few?

One more thing: how about an ifconfig -a on the host?

comment Using two network interfaces for FreeBSD VM
Here is the information I'd get to troubleshoot this (just paste it into the question, not the comment): To make sure you are starting with a clean slate: do the following on both the guest and on the host: 1) sudo arp -d 192.168.1.129, .109 and .130. 2) get arp -an from both (should be empty, except for the permanent entries which are owned by the system). 3) ping .109 and .129 from host. 4) Get arp -an from both. 5) down em0. 6) arp -an on both. 7) repeat step 1 (delete arp entries everywhere). 8) ping .129 from host. 9) get arp -an from both.

comment Using two network interfaces for FreeBSD VM
The host arp may be the same, but is it right? My guess is that this works in your Ubuntu system because of a thing called arp flux (google it), but I can't tell without more information. I believe what is happening is that when em0 is up, the host thinks that both .109 and .129 are at its MAC (ending in 4d:32). When em0 is down, the host still has that information cached, so connectivity to .129 fails. I'll post the steps I'd take to troubleshoot this in the next comment (not enough space here).

comment Using two network interfaces for FreeBSD VM
How about arp -an on the host OSX system before and after? If you do "arp -d 192.168.1.130" in FreeBSD, then ping, then look at arp -an again, what does it show? My guess is that the host/guest are getting confused about which interfaces they should communicate on.

What does ifconfig -a show on the guest before and after you bring em0 down? What does arp -an show on the host and on the guest when things are working and when they aren't?

comment Will a freebsd installation run on a different system without reinstalling?
@Chris, I've haven't attempted it since 5.X days, so no. And with a custom kernel, not GENERIC, which will make a huge difference. But good to know that it usually works out well. (Although the OP needs to take the time to copy the important bits anyway, cause neither operation should ever be done without a backup.)

I think the real question should be: "is it worth it to attempt a move?" Unless there is something really really special, my guess is that you'd be better off just installing fresh and copying over what you need.

comment Google Apps as SMTP relay?
Why not just configure your clients to send directly to google, instead of through your relay? I don't see why you think you need your local Kerio server anymore at all.

comment Updating vSphere 5?
Sorry, I added an answer and then realized I completely misinterpreted the question. I believe you are looking for the VMware Update Manager, which I'm not sure is still available without vCenter.

comment Windows VMWare Server 2.0 Connect CDROM from command-line
I'm not sure, I don't have a Windows machine with Server installed on it to look around. Maybe something in c:\program Files\VMware? You could also look for vimsh.exe or any vmware-*.exe to find possible locations.

comment DIG connection times out DNS
@mailq actually, it could be a firewall issue, if nslookup does a query over UDP and dig does it over TCP (which is often what happens, because dig is requesting more information than a single packet response will allow).

comment What does this mean?192.168.2.2 in use by d8:a2:5e:41:aa:6e, DHCP Server 192.168.2.1
Or, depending on the environment, find the offending device that was configured to conflict and terminate it with extreme prejudice.

comment Performance differences between Cisco Catalysts?
Keep in mind that those two linked articles are 6 and 8 years old, respectively. The information in them is likely quite out of date.

Thanks Nils. I've tried several of the different options for PV drivers, and have yet to find one that could in any way qualify as stable in Windows XP 32bit.

I want to fix it. E.g. DomU "A" always gets DomID "3". I'm running debian squeeze with Xen 4.0.

Which linux distro? Last time I tried this on Debian Squeeze, it couldn't be done without serious effort, as the drivers were only available for a limited number of platforms.

comment Change or set domain id on a vm
Well, for one, vifs and taps are named bades on the domid, and I'd like to make them deterministic for certain VMs. UIDs aren't going to help with this, and they also aren't displayed with the standard tools such as "xm list", so I'd have to build a map so I know what Dom IDs are associated with which UIDs.
