the VMware workstation reliably breaking every 2 to 3 kernel updates and

better plan. I used KVM many years ago and it was not quite as reliable &
easy to work with as I needed. I assume it's gotten better?
What VM's do you need, e.g., do you need to run Windows or just linux
VM's? Is there are reason to rule out VirtualBox and lightweight tools
(LXC -- Docker, LXD, etc)?
- does anyone have experiences good and bad with KVM? Any gotcha's or
common issues I should be aware of?
I've had good experiences, but roghly 5 years ago) using VMware VM's to
provide linux in a Wiindows-based teaching lab. The same VM's can be run on
a Linux or MacOS host to prepare teaching material. KVM at the time was
considerably slower than VMware.
- Anyone have experience with both KVM and VMware? opinions on which is
better, more stable, etc?
I switched to VirtualBox after trying VMware and KVM, and then from VB to
LXC, but I'm no longer running workshops, just software testing across
multiple linux platforms. Disk space requirements of VM's gives LXC a
- Is is easy / possible to convert a VMware workstation VM to a KVM?
Looked at this once, but had some issues with the device drivers (VM was
using a disk controller that KVM didn't support).
- With VMware I get the vmnet network and I don't have to do anything
other than select nat, bridged, etc to get networking in place for a VM,
even if I want to access te VM directly from another machine (i.e. not the
local only network). Is this true with KVM as well?
- If I decide later to remove it does it remove cleanly? I dislike the
vmnet & other bits VMware leaves around even after an uninstall
You might find it better to host VM's on a minimal install of a stable
distro (CentOS 7) and run
unstable OS's (e.g., Fedora) in VM's or containers.
