Turn off options in private DC for perfomance? costs and stability

[slavonnet]

All hosts in private network, all events logged. Secute levels overhead and implemented in net/adm level.

Need support

1.. selinux=0 boot options.

Updates can issue denys, bugs for new logic. Many muddle inhouse installs not need it Profit is s,mall. Fails costs is big .

2. migrations=off.

3. All VM must work in fll perfomanse If user get root from guest VM i will offer it ! ) Agan - costs for perfomance is biig. Cost for cavets is little.

4. Turn off all power save and other llatancy issues. C0 state folrever.

emergy cost s muchs smaller than time

4. Support use last kernel/tools for new features!

Time is costs, New features save time

5. Move all support services to containers/ nsmespaces.

No chance use host for NAS or docker. you tools logic use all host but server can be userd for more tasks and custom workload

6. Add NoTLS/SSL install option

no need overhead amd cpsts

7. Add support for change/upgrade hostd engiine cfgs (bios type/max cpu/ sorage buus).

8 . Add support for overrite XML in VM cfgs for customs

9 Add backup api calls scripts for VM, Schecluder, UI

10. Add options for DISK image RQW/QCOW2 convers, shrink

11/ Add fast path to full backup without cloning, moving and exportion OVS.

i Want gzipped snapshot download or expoet without cloning vm (with leases, permissions and other itemss). Cloning snapshot for new VM is most stupid and overhead task. Why need clone all and then delete all objects? In most cases used backup/download/save. Clonning for clonning used in 1% cases!

12. Add exceeptpns collector and sending with KB if have workaround.
