hello ,
i did a kvm guest with virt-manager and installed windows server 2016.
performance settings for the disk: hypervisor default for cache & io
mode
i added a 2nd disk to the guest , also with hypervisor default settings
on cache & io mode
Under disk settings in windows server 2016 i set "format whole disk
NTFS"
i did not choose the "quick format" option.
when windows is formatting this 1TB drive the performance on the
virtualisation host goes down
loging via ssh take ages, top take 2 mins to start up.
the physical disks are connected to a raid controller LSI and FS on
virtualisation server where the qcow2 files are is XFS.
DO i have to set another options for "performance options" as
"hypervisor default" to keep the system performant on formatting the
disk?
thanks for any hints.
marko
