Are there any alternatives to Virtualbox for slackware 15?

These two come to mind..

Qemu - https://www.slackbuilds.org/reposito...0/system/qemu/
VMware Workstation Pro (Pro version is not free and the free version is not very good IMO)

Thanks.

Nikos Giotis has produced an excellent bash script tool called 'vms' which configures qemu in the easiest way possible. Beats virsh by a mile way less complicated as it runs qemu barebones.

All that's required is vde2, qemu from sbopkg and tigervnc from /extra

vms at slackdocs

Hello, I used to work with qemu and virt-manager.
I tried quickemu too which provides a different/quick way to install VM/OS, dependencies are relatively easy to install on slackware (https://github.com/quickemu-project/quickemu)
Good luck

I've had good results using VMware Player. I've been using it for years.

Although the quickemu and vms sounds very interesting. If I had more spare time I might play with it.

Other VM solutions I've tried would work but odd things like CPU spiking to 100% randomly or just running slow always led me back to vmware.

However I did have to do a bit of tweaking to vmware to make it behave. It too would max the cpu and I could never figure out why.

I did these two things to make it finally run nicely.

1. Add some settings to the .vmx config file:

mainMem.partialLazySave = "FALSE"
mainMem.partialLazyRestore = "FALSE"
priority.grabbed = "high"
priority.ungrabbed = "normal"

MemTrimRate=0
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"
mainmem.backing = "swap"
mainMem.useNamedFile = "FALSE"
prefvmx.minVmMemPct = "100"

2. add two lines to /etc/rc.d/rc.local

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
