Implement support for virtio plan9fs filesystem passthrough in QEMU Make use of the existing <filesystem> element to support plan9fs filesystem passthrough in the QEMU driver <filesystem type='mount'> <source dir='/export/to/guest'/> <target dir='/import/from/host'/> </filesystem> NB, the target is not actually a directory, it is merely a arbitrary string tag that is exported to the guest as a hint for where to mount it.

Add VIR_DIV_UP to divide memory or storage request sizes with round up Use it in all places where a memory or storage request size is converted to a larger granularity. This avoids requesting too small memory or storage sizes that could result from the truncation done by a simple division. This extends the round up fix in 6002e0406c338668ea0ecbfeb6c1ef20a8b67efe to the whole codebase. Instead of reporting errors for odd values in the VMX code round them up. Update the QEMU Argv tests accordingly as the original memory size 219200 isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change it to 219100 and 219136. Use two different values intentionally to make sure that rounding up works. Update virsh.pod accordingly, as rounding down and rejecting are replaced by rounding up.

Introduce <driver> under <filesystem> to support open-by-handle VirtFS allows the user to choose between path/handle based fs driver. As of now, libvirt hardcoded path based driver only. This patch provides a solution to allow user to choose between path/handle based fs driver. Sample: <filesystem type='mount'> <driver type='handle'/> <source dir='/folder/to/share1'/> <target dir='mount_tag1'/> </filesystem> <filesystem type='mount'> <driver type='path'/> <source dir='/folder/to/share2'/> <target dir='mount_tag2'/> </filesystem> Signed-off-by: Harsh Prateek Bora <harsh@linux.vnet.ibm.com> Signed-off-by: Eric Blake <eblake@redhat.com>

Add new attribute wrpolicy to <driver> element This introduces new attribute wrpolicy with only supported value as immediate. This will be an optional attribute with no defaults. This helps specify whether to skip the host page cache. When wrpolicy is specified, meaning when wrpolicy=immediate a writeback is explicitly initiated for the dirty pages in the host page cache as part of the guest file write operation. Usage: <filesystem type='mount' accessmode='passthrough'> <driver type='path' wrpolicy='immediate'/> <source dir='/export/to/guest'/> <target dir='mount_tag'/> </filesystem> Currently this only works with type='mount' for the QEMU/KVM driver.

Do not generate security_model when fs driver is anything but 'path' QEMU does not support security_model for anything but 'path' fs driver type. Currently in libvirt, when security_model ( accessmode attribute) is not specified it auto-generates it irrespective of the fs driver type, which can result in a qemu error for drivers other than path. This patch ensures that the qemu cmdline is correctly generated by taking into account the fs driver type. Signed-off-by: Deepak C Shetty <deepakcs@linux.vnet.ibm.com>
