Unlike installing Linux Integration Services, Hot-Add support is not enabled by default after installing hyperv-daemons.
Create a file /etc/udev/rules.d/100-balloon.rules. You may use any other desired name for the file.
Add the following content to the file: SUBSYSTEM=="memory", ACTION=="add", ATTR{state}="online"
Reboot the system to enable Hot-Add support.
See Note 8 on Supported CentOS and Red Hat Enterprise Linux virtual machines on Hyper-V

I just use spaces. It works better with searches.
I used to not use spaces, but it really doesn't matter anymore.
When downloading files from sharepoint, it replaces spaces with "%20" that's another reason I avoid spaces.

I've been assigned to record several video sessions for our Program Advisory Committee that we are hosting at the College. Not complaining, free tasty food from Zupas is provided.
It has an electric cable, therefore he must be responsible for it.
I love being behind the camera for any project though.
There are some good information from employers about what they expect from students when it comes to experience. And what the school will need to help the students to succeed.

I use a combination of underscore, hyphens, uppercase and lowercase. And ever since I started juggling between Mac, Windows and Linux, I've been avoiding spaces.
Not sure if you noticed but most Linux and Windows iso downloads use a combination of hyphens, underscore, uppercase and lowercase.
@matteo-nunziati said in What Are the Latest Virtualization Platform Recommendations:
@scottalanmiller I've recently looked at the SLES installer and it seems it is able to support Xen. Not sure about opensuse.
My idea was: why use XS if I can install it on a minimal suse leap? I've never used xen so I do not know if XO is able to deal with Xen over suse.
This would be a nice way to go out of the really strict/limited apporach of XS. And anyway it would be way more close to what one does with centos minimal install + libvirt/kvm.Currently I'm using hyper-v + altaro. I've just setup a replica server using the build-in replica service and I'm going to test it (and write a little bit about the process). Altaro is great but hyper-v is really MS stuff:
- dynamic memory has frozed ALL of the VMs on my host (even win ones), leading me to go the static memory way.
- everytime I read about issues with a potential update a million of guys jump out of the blue with the wierds issues, scarrying me. I always pray when an update is to be installed.
- performance is not top notch (minor issue here)
- now and then the VM manager freezes...
- and honestly poweshell is way worst than unix-like apps + bash/sh
All in all it seems the classic lack of QA and NIH syndrome from MS. But for sure it does the job and the SW ecosystem is wide.
Updates pretty minor when using Hyper-V Server instead.
Dynamic Memory works great as longs the hyperv-daemons for Linux is installed and also configure memory ballooning.
I have experienced Manager freezing because of antivirus.
PowerShell does take awhile to get use. I've been forcing myself to use PowerShell exclusively. I understood it more than I did with vbscript.
Your Ubuntu Server DNS setting is probably configured with your DNS Server IP.
@Shuey said in FOG Server IP Keeps Changing in DNS!:
@black3dynamite "Nonsecure and secure"
Have you already try setting it to secure only and then delete dns record?
@Shuey Do you have Dynamic updates set to Secure only or Nonsecure and secure?
Plus knowing how to manage your hypervisor without the need of a GUI will help a lot. Especially when you are unable to use GUI.

@hobbit666 said in What Are the Latest Virtualization Platform Recommendations:
But I found HyperV there was a lot of messing to get a workstation to talk (especially if your on a different network/domain)
This might of gotten easier since the last time I tried HyperV
but it put me off.
This! When I first switched to virtualization it was Hyper-V, and getting it to talk to my workstation was so unnecessarily difficult, I wanted so badly to just join it to the domain. 5Nine is awesome and totally remedied the awkward communication/credential problems. I ultimately bailed on Hyper-V and switched to XS around the same time I switched to Windows 10. We had just gotten a new virtual host and I wanted to try something new, and not paying the $350 a year for the 5nine license was a bonus.
I can't for the life of me get into XO though, XenCenter just works and does everything that I need it to do. Maybe I like it because I was used to 5Nine? I don't know. It seems to be a pain to log into the web interface and fumble around trying to find the stuff I need when I'm already used to XenCenter. I haven't given it a true chance though.
For what it's worth, I've had zero issues with XS since switching. For me, it's been a far better experience than Hyper-V was.
Believe it or not, managing Hyper-V via PowerShell is more straight forward than setting up the right permissions and settings in order to use Hyper-V Manager.

@Francesco-Provino said in KVM Installation and VM Creation on Fedora 25:
But, really, don't install a guest in the '90s way with KVM, instead use a proper tool like virt-builder.
The old way of install a guest is completely unneeded in a virtualized/cloud world; instead of installing through an ISO, a procedure that is slow and requires kickstart/manual intervention, you can just use a cloud image pre-built and optimized to run as a virtual guest and inject the customizations (credential, additional software, config) with tools like virt-builder.
AWS and the other cloud providers works this way.
How would I use virt-builder to install a windows guest?

@Francesco-Provino said in KVM vs XenServer:
I think that the only thing I truly miss in KVM is not a fancy GUI, but instead a stateless host OS 'a la XenServer/ESXi' that I can safely deploy to a usb drive. Something like CentOS atomic host should be good, but focused on KVM instead of Docker.
You should be able to do a USB install and ship the logs off to somewhere else. Then just mount your disks/volume for the guests.
I've been thinking of trying that but been too busy/lazy.
Not having a swap partition or swapfile on the USB too.

@Francesco-Provino Have you used oVirt?
I've used it in my home lab. It was slow. Took a while to clone. Interface was a little slow. KVM on CentOS 7 I can fully clone my template and start the clone in around 3-4 seconds.
Was it slow due to your hardware not being capable?
oVirt is Red Hat's virtualization management platform & it is supposed to be capable?
I did do the all in one install but it has 96GB RAM and 8 cores (16 vCPUs) and 10K SAS drives. I'd hope it would run decently well on that.
I thought the all in one is only available via their live cd version just to get an idea about it? Setting up a separate host for the engine and the other for the node works better.
Does this happen on a clean install before updating?
@stacksofplates
not sure about unzip but tar is also not installed on the minimal install too.
