And since discovering Mangolassi, XenServer seems to be only popular here when Xen Orchestra is being used with it.

that's the only context in which it makes sense. That's its one main management tool.

But saying that, you could say the same kind of thing for Vmware ESXi... it's only popular with vSphere to manage it. Of course, you need something to manage anything. When you have a management tool that is free and really good, there is no need for anything else and/or the two just become associated. That XS is only popular with XO just makes sense, as it is open, free and very powerful. XS has to have some tool, and that one is so good that no one else tries to compete.

Besides not supported better file systems for vm storage especially when using thin storage. I'm never a fan XenCenter it gets the job done but I much rather do things via CLI. I really hope XenServer devs integrated XO soon.

I think they should focus on things like not using ext3 first.

Totally agree. They should really have two version of XenServer. One can be the current one. And the other will include things like ext4, xfs, LVM thin.

@scottalanmiller said in KVM vs XenServer:

Well, flexibility is a big one. KVM is just the hypervisor itself, so you are building out your own ecosystem choices. XS is the stack, so you are limited to the choices in that stack. XS is good and has a lot of good things baked in and some good add ons, added on but it also removes some flexibility, makes some dumb choices and slows down development (compared to straight Xen.)

KVM is definitely getting way more attention and is gaining on Xen all of the time. Xen has some cool tech coming down the pike that will potentially leapfrog it over KVM in terms of Linux virtualization performance, but right now KVM has the lead in a small way with Linux and a large way with Windows where KVM has always focused.

So in performance they have rough parity with Linux workloads, and KVM currently has the edge in Windows? It seems odd to me that KVM has focused on Windows. I would've thought the other way around.

Basically Xen owned the Linux performance space by doing PV so KVM would have to have reinvented the wheel just to compete, but they were able to go after non-PV workloads (like Windows) pretty heavily to differentiate themselves. So mostly just market pressure.

How much of a Linux performance difference nowadays between Xen and KVM? Boot up time, IOPS, etc...

KVM has a slight edge right now. But it is expected to be lost in the future.

Lost in the future from XenServer or Xen or Both?

@JaredBusch

Based on the management tools that is available to each hypervisors, free or paid. What is your preferred hypervisor?

Sounds like an unbalanced load on your APC.

Its going to take time for XenServer to catch up. Every since it became open source all that I've read so far is mainly performance improvement. Which is not bad at all but compare to what is being offered with KVM and Hyper-V.

And since discovering Mangolassi, XenServer seems to be only popular here when Xen Orchestra is being used with it.

When you reset networking stack, did you do all three?

Reset WINSOCK:
netsh winsock reset catalog

Reset IPv4 TCP/IP:
netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP:
netsh int ipv6 reset reset.log

@JaredBusch said in Linux Lab Project: Building a Linux Jump Box:

Additional steps that are often interesting are to add two factor authentication to the Jump Box, such as Google Authenticator.

Anyone know a solid guide for adding Google auth to Fedora before I just google one up in the morning?

This might help getting you started. Although it's based on CentOS using yum instead dnf.

@scottalanmiller it tAkes a couple of refreshes

Well written. I like that it covers history back to the IBM 1960s era, and clarifies what T1 and T2 are, and makes it perfectly clear that Hyper-V is T1 by both direct statement and description.

Under type 2 examples, KVM is listed has a type 2.

The list should include distros that supports Wayland or Xorg.

There has to be a Linux disto that works.
This is the only one I can think that might work. Manjaro

Windows Configuration Designer seems to be the tool that helps with removing pre-installed software.

I made a PowerShell script to run that cleans it all up automatically. Well a .bat that runs it. I have it somewhere on SW, but it's out of date. I'll find the one I have that's more up to date and edit this post.

I honestly do not care if the crap is there or not.

But sysprep fails with some of it there. That is the problem I have with it. I just want a fucking image with my basic stuff pre-installed. I could care less if the user has Candy Crush. That is a managerial issue.

Get-AppxPackage -AllUsers *Candy* | Remove-AppxPackage
Get-AppxProvisionedPackage -Online | Where-Object {$_.PackageName -Like "*Candy*"} | ForEach-Object { Remove-AppxProvisionedPackage -Online -PackageName $_.PackageName}

That's basically all the powershell script contains. Removes about 30 different things. Probably more with the Creators update. But you need to uninstall it from both the "allusers" and "online". You'll have to reboot for it to be completely gone.

If you don't remove the app using the bottom "-online" part, it'll be there for new users.

I'm going have to update my scripts as I just gave a presentation on this last night. Thanks.

Also, if you look at the fullpackagename property of the appx, if the suffix is cw5n1h2txywey then it is system dependent and cannot be removed. The some of the XBox appx packages are that way.

I noticed that if you want to keep an up to date list of Crapware MS sticks on, like after big updates such as 1703 and the like, you'll need to run a command to get a new list of apps to see if you need to add any to the list. This is what I use:

Get-AppxPackage -AllUsers | Select Name | FT

and

Get-AppxProvisionedPackage -Online | Select DisplayName | FT

Any harm removing all AppxPackages and AppxProvisionedPackages?

I assume you don't want to pass ctrl+alt+delete to avoid accidentally restarting the VM, correct?

You assume wrong.

CTRL + ALT + Left Arrow ( or Right Arrow)

is the default key combo on Korora Cinnamon to switch workspaces. Probably similar on other desktop environments.

Yes, this is why.

Switching to a different workspace while in a fullscreen VM would be awesome without having to go out of fullscreen mode first.

Switching between workspaces on Gnome 3 works.
