Hi all, hope this is the right place to ask this.
>From my understanding of virtio-pmem it can be used to bypass the guest page cache, so that the host is in control of the guest page cache. I have successfully run QEMU with a virtio-pmem device managing my drive. However, while testing (e.g. creating files) I still see the guest page cache growing, the same as without virtio-pmem. I would have expected to not see the guest page growing, as virtio-pmem is supposed to bypass it. I thought that the access through the virtio-pmem driver in the guest would circumvent the normal page cache mechanism. Does anyone know if my understanding of what virtio-pmem should do is wrong or is there maybe some guest kernel specific configuration that I need to do in order for this to work? Best Regards, Marco
