Hi,
Before switching to io mode=native, I wanted to check if there are any
disadvantages or potential problem with this setting.
I virtio-blk data plane required to use this setting effectively? (as
illustrated
here:http://blog.vmsplice.net/2013/03/new-in-qemu-14-high-performance-vir...)
Is there a requirement on the host kernel (eg minimum version)?
Is this a stupid question or does no one use native io mode? Please let me know
dataplane is not required for io=native. io=native is used quite often in
practice, just when the VM is using a host block device as storage. That's
when virt-manager sets io=native at least, as recommended to use by the qemu devs.
