I like KVM, though I agree with Scott that XenServer is probably the first option you'll want to use; especially if you'll be seeking assistance from this community. A lot of the common tools and packages (libvirt and virt-manager come to mind) are compatible with both Xen and KVM-QEMU. Once you've got a familiarity with XenServer, a lot of what you've learned will translate to managing a KVM hypervisor.

I have a user working remotely that is experience a strange issue with Windows 10 File Explorer. Whenever he tries to open or save a file it takes an unusually long time to access anything in File Explorer. We've tried disconnecting all network shares that are inaccessible and changing the behavior of "Quick Access" to only cache local items and the behavior persists. However, if he turns on Airplane mode it operates normally... As soon as he turns wifi back on the problem reappears.

Has anyone else experienced this? He has a nearly identical personal laptop that does not have these problems. The only major difference between the two is his work laptop is joined to our domain and his personal laptop is not. I don't have any other users (including myself) that experience this when working outside of the office.

Any ideas?

For conference room designed for less than 10 people I use a Logitech BCC950 ConferenceCam.

I mean, it isn't like he's using HDDs; everything should still be within warranty on landing right?

Probably around 700-ish CentOS 7 boxes, a few hundred CentOS 6, and 50-ish CentOS 5 boxes running some legacy applications we hope to phase out soon. I have heard mentions of some Ubuntu boxes somewhere, but not in production.

I work off of OS-X.

@scottalanmiller What made you decide against it? We are getting ready to migrate to teams from HipChat.

@wirestyle22 I think that should work. As long as you can see the disk you should be able to use LVM's pvcreate to create a physical volume and then add that volume to the volume group that is associated with your logical volume.

pvs and pvdisplay will show pertinent information in regards to your LVM physical volumes.

vgs and vgdisplay will show volume group information.

lvs and lvdisplay will show logical volume information.

I prefer KVM/QEMU. It's worthwhile to invest time in learning all of the tools to manage everything from the CLI before trying to rely on any of the GUI based tools like virt-manager/virt-viewer.

I only interface with KVM on my home test environment now, but these are the tools I most frequently use. And aside from virsh, most of them are rarely used outside of a script.

• virsh
• qemu-img
• virt-clone
• virt-sysprep

Also, installing Vim and typing 'vimtutor' at any terminal will launch an interactive beginner's tutorial on Vim.

I've seen this behavior a fair amount on systems where log rotation for java applications is misconfigured. Log files are removed while the java application is still writing to them so it shows the file being deleted even though the connection to the inode is still held open.

A reboot is usually the quickest way to release the inodes.

@scottalanmiller it’s a Mac

Use Python.

Sadly all I know about Python is it’s a snake...

Use bash?

Before you take on any new work I would recommend reading "Time Management for System Administrators" by Tom Limoncelli.

https://www.goodreads.com/book/show/376236.Time_Management_for_System_Administrators

Put into practice the principles discussed in the book and start organizing your time.

A favorite quote of mine as of late is: "How you do anything is how you do everything". Don't take on a project or task if you can not afford to give it the time, attention, and resources that it deserves. Failing is okay, but setting yourself up for failure is a waste of time and potential. Always keep a focus on attention to detail and maximize your time and efforts.

MS Office = VIM
Desktop email = mutt
Notepad = VIM
Softphone = Slack
Notepad++ = VIM
MS Publisher = VIM (or LibreOffice if your employees are all underachievers)
ScreenCapture = Stop using GUIs
Visio = LucidChart
OneNote = VIM (or Evernote for the underachievers)

I primarily work from a MacBook Pro and use a combination of the following:

• iterm2
• tmux
• FISH shell

You could use AWS-EC2 free-tier linux instance to build an OpenVPN server and encapsulate the traffic in SSL. This is kinda shady, and depending on your locale could be considered less than legal, but it works.

fix't! Thanks!

@scottalanmiller It's okay to call them "West Vur-jeye-ners" if we use an Appalachian accent right???
