What is a good virtualization solution for SMB?

Question

Virtualization

Good day,
Please advise a virtualization solution for SMB that meets the following criteria:
1. Reliability, stable operation with minimal intervention in the work of the hypervisor, in the "set and forget" style (I will never forget how I had to dig into the guts of Hyper-V, a couple of years back, solving problems with the VM on the host).
2. Availability of a sane infrastructure management system.
3. It is highly desirable to be able to backup the VM on the host using commercial or similar software in the style of Veeam Backup & Replication, etc. Or the presence of built-in backup functions, without crooked scripts and other hemorrhoids.
4. Having a live community is extremely useful in troubleshooting.
On the host, it is planned to launch a VM running both MS Windows and Linux. What is not required from the capabilities of the hypervisor - HA, Fault Tolerance, vMotion and others like them. The second host is definitely not expected in the near future, so the presence of this functionality is not critical.
Interesting open source solutions such as Proxmox, XenServer 6.2, XCP... There is no experience with them (although learning is not a problem), it is interesting to hear an opinion about them regarding work in production.

Answer 1

there is VirtManager on KVM,
I advise you to use Citrix XenServer, it has a management utility that is very convenient in quality KVM and Xen do not differ, KVM loses a lot in terms of ease of management, xen does not know how to soft raid out of the box

Answer 2

I have been using xen for several years now. Both linux and windows with PVGPL are spinning - there are no special problems. There are a couple of bugs / features in the xen catfish, but they can be bypassed, the wiki says about them. I'm looking at KVM because. its architecture is simpler, and the functionality is not much different from xen.

Answer 3

For a couple of years kvm - the flight is quite normal, there are some nuances, but where they are not, you can first try on Proxmox (works out of the box). You can also look in the direction of esxi, but there with backups it’s either expensive or everything is very sad, well, I personally caught a noble fakap on it, I don’t want to anymore. You will hardly find a more crooked solution than Hyper-V, so the choice is rich.

Answer 4

What about backup?

Answer 5

And if it's not a secret, can you tell us more about the fakap? :)

Answer 6

Regarding KVM, what are the means by which you manage the virtual infrastructure? CLI is good, but not always convenient. Or does everyone use Proxmox as a "strapping" to KVM?
