LiLi virtualization fails

I downloaded the current 18.04.2 Desktop ISO, checksummed it, and ran LiLi from Windows 10 to generate a LiveUSB. In Step 4, I selected the Virtualization feature shown at the LiLi link (see ‘No reboot required’).

LiLi's Step 4 dialog box

I can boot from the LiveUSB and run Bionic AOK, but the virtualization feature fails when I go to the VirtualBox folder on the LiveUSB and launch

Virtualize_This_Key.exe   

I do have Local Admin rights on my Windows 10 Pro machines (tried on several, both RS4 and RS5).

I left a request for support one week ago on the LiLi website; echo answereth not, no response.

Anyone use this feature? Any special tips to make it work on a supported Ubuntu? Or is this app pining for the fjords?

Infrastructure – different variants. What are the advantages of the virtualization layer?

The infrastructure that I see most often:
First infrastructure

Is the infrastructure below not simpler and better?
Is this the future or am I wandering the forest?
Second infrastructure

The first infrastructure.
– Many layers use more resources?
– Looking at the whole is more difficult and requires knowledge of more tools?
– In which layer should the applications be scaled?
– It’s harder to find performance errors?

Considering how computer hardware and I / O devices work, more conscious allocation of resources should give better performance than VM (e.g. join Intel Xenon and Pentium 4 then assign VCPU to different machines)

Second infrastructure
– At the kubernetes level, we can also scale horizontally depending on the needs, we can also set resources for every container.
– OS, thanks to Linux users accounts, allows for secure administration.

I have one doubt which is better. Applications that grow over time and need to keep increasing the space on the disks.

How to design virtualization infrastructure

I have a university assignment that asks you to design the infrastructure for a company that wants to virtualize their servers.

It asks for number of hosts required, number of VMs running on each and what each is running, cpu, ram, storage etc.

It provides you with a list of their current non-virtualized servers to work from (shown at end of post).

I don’t understand how I’m supposed to design the infrastructure without running any tests first to determine how much cpu/ram/storage each server needs. Wouldn’t it just be a complete guess?

Unraid Virtualization: gpu is in use by driver QEMU and Windows 10 “shutting down, reason=destroyed”

I am a total noob to the world of vm but I have gotten past creating an unraid array and I am beginning to create vm’s

My pc contains an i7 8700k, GTX 1080, and a GTX 980 ti.

My problem is that whenever I try to launch a windows vm I created it looks fine until I check out the logs. I keep getting this:

2019-04-23 01:59:46.696+0000: starting up libvirt version: 4.7.0, qemu version: 3.0.0, kernel: 4.18.20-unRAID, hostname: Tower 2019-04-23 01:59:46.696+0000: Domain id=1 is tainted: high-privileges 2019-04-23 01:59:46.696+0000: Domain id=1 is tainted: host-cpu 2019-04-23T01:59:46.726907Z qemu-system-x86_64: -chardev pty,id=charserial0: char device redirected to /dev/pts/0 (label charserial0) 2019-04-23T02:10:46.942420Z qemu-system-x86_64: terminating on signal 15 from pid 2972 (/usr/sbin/libvirtd) 2019-04-23 02:10:48.343+0000: shutting down, reason=destroyed 2019-04-23 02:12:53.617+0000: starting up libvirt version: 4.7.0, qemu version: 3.0.0, kernel: 4.18.20-unRAID, hostname: Tower 2019-04-23 02:12:53.617+0000: Domain id=8 is tainted: high-privileges 2019-04-23 02:12:53.617+0000: Domain id=8 is tainted: host-cpu 2019-04-23T02:12:53.647026Z qemu-system-x86_64: -chardev pty,id=charserial0: char device redirected to /dev/pts/0 (label charserial0) 2019-04-23T02:18:55.352186Z qemu-system-x86_64: terminating on signal 15 from pid 2972 (/usr/sbin/libvirtd) 2019-04-23 02:18:56.753+0000: shutting down, reason=destroyed 2019-04-23 02:21:07.385+0000: starting up libvirt version: 4.7.0, qemu version: 3.0.0, kernel: 4.18.20-unRAID, hostname: Tower 2019-04-23 02:21:07.385+0000: Domain id=10 is tainted: high-privileges 2019-04-23 02:21:07.385+0000: Domain id=10 is tainted: host-cpu 2019-04-23T02:21:07.414616Z qemu-system-x86_64: -chardev pty,id=charserial0: char device redirected to /dev/pts/0 (label charserial0) To me it looks like the startup is attempted many times until it gives me “shutting down, reason=destroyed” if anyone has any experience with this let me know.

My other problem is with my second vm giving me this error code:

PCI device 0000:01:00.0 is in use by driver QEMU, domain Vr Computer 1 My understanding is that because unraid is using my first gpu and not allowing my second vm to use the second gpu in my computer.

If anyone has experience with gpu vm issues help would be much appreciated.

how to check if Xen support hardware virtualization?

I am try to check if xen in ubuntu 18.04 support virtualization. By following this comand:

$   xm info | grep caps  

I am follow step 5 of this tutorial: Check virtualization capabilities

The output of this command in my pc is:

 eda-2@eda2-ThinkCentre-M82:~$   xm info | grep caps ERROR:  A different toolstack (xl) have been selected!  

What does mean? what i should to to check virtualization capabilities? Pls help me, I am beginner in ubuntu.

Thanks.
