I am not sure how that is worse. I would imagine in a system with liability for a home inspector he would have to pay for the service call when the repair folks do their initial inspection and estimate. Since he would have cause unneeded work.
In such a system the home inspector would get insurance and bad ones would not be able to continue to get those policies.
Is there a reason you believe you will not want to stay in this home?
I for instance bought a ranch, since stairs will become a problem with age. I have had many relatives forced to sell homes they lived in for decades for that exact reason.
Mine missed major issues. Main line had tree roots and the issue was apparent if you ran the water in two locations at once. So shower and sink near washing machine, for example, the water backed up into basement or at least flowed out very slowly. The furnace short cycled and had a cracked heat exchanger, which a carbon monoxide detector should have found.
There were also many minor issues like the fact that the kitchen sink drain was improperly repaired and leaking. Also everything was done on the cheap by that last owner. So I have had to replace failing sink/toilet/fridge water lines and the like with steel or copper. These minor items are my fault for not noting during the walk through, but it would have been nice if he mentioned it.
We are talking about $500-$1000. An HVAC tech will want about $100 to clean and inspect, the roofer and contractor about the same. The plumber will vary, but even with cameraing the main you are looking at no more than $300 for him.
Why would you buy a home that is not your last? I have no intention to sell my house unless I am forced to move by my job. Perhaps more than the expected number of children could also motivate me to get another home, but unlikely. I shared a bedroom and my offspring could do the same.
You would be far better served by getting a plumber, a roofer, a HVAC tech, and a general contrator to look at the place. It would not cost you anymore either. The home inspector is just there to rubber stamp the house so you can get a mortgage. Anyone who is not willing to take some liability might as well not look at the place at all.
Everyone should. They are worse than used car sellers. The only folks worse are home inspectors. Even if you select one yourself, and pay him yourself he will still miss tons of stuff and try to give you the best impression of the house. This is because you are not likely to need future inspections but the realtor is. Also in many/most states they are only liable up to the cost of the inspection.
Making realtors and home inspectors at least as liable for issues with the property as used car salesmen are would be a huge improvement.
Very recent? It has been that way since before I was born and I am not exactly a spring chicken. My german mother gave me a non-german name. I had German granduncles that had non-german names. So in this case recent has to be right around 100 years or more.
I agree with your first point. All the current VM management tools do not prevent this behavior. I honestly am not in favor of that level of handholding, but I can see where some might be.
I did not say different was bad, I said why I did not like it. For the record I speak german, badly, and my name stays the same.
There is no need to change a name to denote a role of a noun. My name is the same when I speak german. Heck, I spoke it with this name before I spoke English.
Indeed. I am not suggesting otherwise. I am only pointing out that VM software is not magic. It does the best it can, but cannot be relied upon to be infallible.
It has nothing to do with handling several servers or not. It has to do with the fact that if one VM can access all the CPUs it can keep them all busy.
The disk is the same thing, if you do not limit a VM to a fixed amount of IO it can simply tie up all access to the disk for another easy DOS attack. This goes for any and all shared resources. Not very hard to soak a 1Gb network link just to be a jerk.
Actually I was suggesting not sharing NICs and using VLANs on a managed switch, if at all possible. So each VM has its own NIC and VLAN. They would not be allowed to talk to each other.
It is not fast nor quick at 2am. Which is when one bored kid is going to try to find out how much fun he can have with an arp black hole or other such silliness.
What about it? Should there be one? Of course it should probably even limit traffic to just http and other services they absolutely must have, there should also be an IDS on their network segment. That does not change the fact that VLANing off these folks is the best practice and that NAT offers nothing extra for this. You would not be trying to protect the VMs, but be protecting others from them.
NAT is not the correct solution to this nor would it help. NAT does not stop anyone scanning outward, the NAT router will setup the address translation just as it should. VLANS are the correct answer. Pulling physical cables is too much work, and cannot be done remotely.
A nice forkbomb in a single VM can cause headaches for the rest of the environment. There have also been exploits to allow one to interfere with either the host kernel or other guests, we have no reason to suspect all those bugs are crushed. VirtualBox is a fine desktop VM software, it is not however suited to this task.
And is utter trash for anything that needs to be scalable.
It is fine for a desktop VM system, but it simply does not offer the management interfaces that other solutions have. Basically the options here are VMware and KVM. The first if you want a shiny GUI the latter if you are ok without one. Both will let you script everything they do, which will be very handy when you need to reset 100 VMs for the next batch of students.
Yeah, I am not called by a different name when I am speaking another language. Even if that language has a similar name. Translating a name does not make good sense.

That does make sense then.

Which is why I also suggested KVM.
Virtualbox is neat, but it is very limited. It might be better to show them something that is actually used in industry.
Indeed. I am not suggesting otherwise.
I am only pointing out that VM software is not magic. It does the best it can, but cannot be relied upon to be infallible.
English is a bad language as well, but this seems pointlessly complex.
We should first fix our spelling, that would improve the language a lot.
I do, but this joker might not.
It has nothing to do with handling several servers or not. It has to do with the fact that if one VM can access all the CPUs it can keep them all busy.

Actually I was suggesting not sharing NICs and using VLANs on a managed switch, if at all possible. So each VM has its own NIC and VLAN. They would not be allowed to talk to each other.
I should have made my proposal more clear.
Then you should be using KVM or Xen.
Virtualbox is not meant for that use and it shows it.
It is not fast nor quick at 2am. Which is when one bored kid is going to try to find out how much fun he can have with an arp black hole or other such silliness.
What about it? Should there be one? Of course it should probably even limit traffic to just http and other services they absolutely must have, there should also be an IDS on their network segment.

You would not be trying to protect the VMs, but be protecting others from them.
That sounds like a terrible way to build a language.
Perhaps it is better neither of those are still in popular use.
No, stop!
NAT is not the correct solution to this nor would it help. NAT does not stop anyone scanning outward, the NAT router will setup the address translation just as it should. VLANS are the correct answer. Pulling physical cables is too much work, and cannot be done remotely.
Incorrect.

Only if you think your VM software is perfect.
I think all the popular products have at one time had exploits that allowed a guest root user to muck with the virt kernel or other guests.
Heck, if you are not smart enough to limit how much resources one VM can take a nice fork bomb is a good way to slow down the whole shebang.
Funny how we don't read those on slashdot, heretic!
Yeah, I am not called by a different name when I am speaking another language. Even if that language has a similar name. Translating a name does not make good sense.
Could they not simply translate it to a letter and number? I am not sure R2 means anything in English.
