2:38 AM

I'm trying to run a 32-bit fork of Debian in a VirtualBox, but I got an error I'd never run into before:

user image

...anyone know, offhand, where I went wrong?

@Shokhet "VT-x is disabled in the BIOS"?

I don't think that's a problem with Debian, but between VB and your host

@Braiam I don't know what that means.

@Braiam It's worked before, but I haven't used it in a while.

@Shokhet well, exactly what it says, that VT-x is disabled in the BIOS, and I'm sure it would need it

Q: How do I enable VT-X?

I'd like to provide a guest OS with multiple CPUs in VirtualBox. My host machine is a quad core HP Compaq and uses the Intel Core 2 vPro hardware. However, when I try to enable the setting in vbox, I get an error that VT-x is not available. Is this something that I can enable somewhere? how do...

virtualbox intel-core2 vt-x

Aha. I don't know where to go to enable VT-x. Do you have any pointers?

@Braiam Cool; thanks!

@Shokhet your BIOS utility

2:45 AM

@Braiam I ran the program (SecurAble) mentioned in the top answer to the question, and was told that my computer is capable of virtualization.

@casey Oh. Duh. Thanks!

10:42 AM

Yeah. Only one machine left to patch for GHOST. And it's an internal dev machine.

1 hour later…

12:05 PM

@derobert Keeping unusual hours again?

@FaheemMitha Yeah. I was going to quickly do some patches & reboots remotely early this morning. Then Verizon decided to take out my Internet connection...

So I came in to the office to do them :-(

1 hour later…

1:11 PM

@derobert Sounds like a pain.

@derobert When I was in the US my net connection was quite reliable - cable internet - Time Warner / Earthlink. Rarely went down. Is that not the case for you?

@FaheemMitha Its pretty reliable—they said it was some maintenance. Which just happened to be at a bad time, its hardly ever down

@derobert ok. mine would go down like once a year on average. maybe less.

Yeah, same here.

@Shokhet check the BIOS perhaps?

2 hours later…

3:15 PM

In my experience, verizon is one of the most terrible providers

I had a DSL line from them years ago and it was nothing but trouble

3:54 PM

@casey What do you use currently?

60/4 over cable

@casey what provider/companyis that?

charter

@casey ok. And how is it?

60/4 :)

its a pipe, data flows through it. not much else to say

3:59 PM

Just a reminder. No answers for this:

Q: RAIDing with LVM vs MDRAID - pros and cons?

In his answer to the question "mixed raid types", HBruijn suggests using LVM to implement RAID vs the more standard MDRAID. After a little investigation, it seems LVM also supports RAID functionality. In the past, I have used LVM on top of MDRAID, and was not aware till now that LVM also suppor...

lvm raid software-raid md

Anthony said he would answer it. I think he was doing tests...

@casey I meant reliability-wise.

oh, no problems with it

@casey ok

@FaheemMitha Try offering a bounty

@terdon I could. But I'm not particularly enamoured of the bounty system.

And it seems like a reasonable question, deserving of attention.

@FaheemMitha the bounty is to convince others of that

4:03 PM

@casey The question itself should consider people of that.

@FaheemMitha Yes, well, things don't always go as planned.

@terdon That's very true.

It's an old question, if you want people to see it, you need to bump it somehow. Offering a bounty is a good way to do that.

perhaps, but lvm/raid/mdraid testing requires a lot of time as it isn't something you are going to do on a live system

It's really more of a sysadmin question, but if I move it to Server Fault they'll just close it.

Hey, maybe I should tweet it. :-)

4:28 PM

@FaheemMitha It's also not a very good question for SE, It is very broad and verging on opinion based (I see you did everything you could so that it wouldn't be but it's still verging).

@terdon True, it is somewhat broad.

4 hours later…

8:25 PM

Yeah, I need to write that up someday... Though in short I'd stick to mdadm.

9:01 PM

hey guys

[user1@hostname]$ ls -lhstr
4.0K drw-r----- 6 user1 group2 4.0K Jan 30 13:44 folder

i'm trying to figure out why user1 does nto have access to "folder"

since he is the owner

any ideas?

@HankLiu chmod ug+x folder

the owner only has the permissions that are recorded, even though he can always change them

Q: Why do directories need the executable (X) permission to be opened?

In my CMS, I noticed that directories need the executable bit (+x) set for the user to open them. Why is the execute permission required to read a directory?

linux permissions directory

9:17 PM

@derobert A sketch would be a lot better than nothing. Did you complete your testing?

@FaheemMitha I think so. I still have the VM image lying around. I hope I took notes, it's been a while...

@derobert so you concluded mdadm was better? any particular reason, or just a bunch of them?

10:00 PM

@FaheemMitha I think it was mainly a lack of management tools, and things like reshape not being supported. Not entirely sure I'm remembering correctly, hence going I took notes...

@derobert "going I took notes"?

I forget what reshape does.

10:25 PM

Sorry, that should be hoping. Typing on a tablet at dinner.

Reshape = change number or size of devices, or the RAID level.

10:41 PM

@derobert ok.

Hi @Seth

Hi @Faheem

11:17 PM

@Seth So, all fired up for the vim beta?

This one can probably be closed - but maybe wait for poster confirmation.

Q: Malformed Release file upon updating Debian 6

I am running Debian 6 and I am getting the following error upon running apt-get upgrade: Hit http://http.debian.net squeeze-lts Release Hit http://http.debian.net squeeze-lts/main Sources/DiffIndex W: Failed to fetch http://http.debian.net/debian/dists/squeeze-lts/Release Unable to find expecte...

Yes, poster confirmed this fixes the problem. Go ahead and VTC.

Poster is probably going to delete the question, so most likely no action is necessary.

11:40 PM

@FaheemMitha Yes, actually.

I'm not sure I expect it to succeed, but I have hopes.

@Seth why shouldn't it succeed? emacs is doing pretty well.

11:59 PM

@FaheemMitha You know, I don't know.
