Hi, Zhenyu, curious about the progress of this series. Is there still some open remaining or a new version coming soon? Thanks Kevin > From: Zhenyu Wang [mailto:zhen...@linux.intel.com] > Sent: Friday, July 20, 2018 10:19 AM > > Current mdev device create interface depends on fixed mdev type,

[libvirt] [PATCH v4 0/5] libxl: PVHv2 support

This is a respin of my old PVHv1 patch[1], converted to PVHv2. The actual code use "PVH" name. The guest ostype reuse VIR_DOMAIN_OSTYPE_XEN, but to request PVH machine, machine="xenpvh" attribute is used. Since PVHv2 relies on features in newer Xen versions, I needed to convert also some older

[libvirt] [PATCH v4 1/5] libxl: reorder libxlMakeDomBuildInfo for upcoming PVH support

Make it easier to share HVM and PVH code where relevant. No functional change. Signed-off-by: Marek Marczykowski-Górecki --- src/libxl/libxl_conf.c | 26 ++ 1 file changed, 14 insertions(+), 12 deletions(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c

[libvirt] [PATCH v4 5/5] xenconfig: add support for type="pvh"

Handle PVH domain type in both directions (xen-xl->xml, xml->xen-xl). And add a test for it. Signed-off-by: Marek Marczykowski-Górecki --- Changes in v3: - update for modified "libxl: add support for PVH" --- src/xenconfig/xen_common.c | 11 +-- src/xenconfig/xen_xl.c

[libvirt] [PATCH v4 4/5] xenconfig: add support for parsing type= xl config entry

builder="hvm" is deprecated since Xen 4.10, new syntax is type="hvm" (or type="pv", which is default). Since the old one is still supported, still use it when writing native config, so the config will work on older Xen too (and will also not complicate tests). Signed-off-by: Marek

[libvirt] [PATCH v4 2/5] libxl: add support for PVH

Since this is something between PV and HVM, it makes sense to put the setting in place where domain type is specified. To enable it, use It is also included in capabilities.xml, for every supported HVM guest type - it doesn't seems to be any other requirement (besides new enough Xen).

[libvirt] [PATCH 09/11] qemu: Detect whether iothread polling is supported

Add a capability check for IOThread polling (all were added at the same time, so only one check is necessary). Based on code originally posted by Pavel Hrdina with the only changes to include the more recent QEMU releases. Signed-off-by: John Ferlan --- src/qemu/qemu_capabilities.c

[libvirt] [PATCH 11/11] tools: Add virsh iothreadset command

Add a command to allow for setting various dynamic IOThread polling interval scope (poll-max-ns, poll-grow, and poll-shrink). Describe the values in the virsh.pod in as generic terms as possible. The more specific QEMU algorithm has been divulged in the previous patch. Based heavily on code

[libvirt] [PATCH 08/11] qemu: Alter qemuDomainChgIOThread to take qemuMonitorIOThreadInfo

Rather than passing an iothread_id, let's pass a qemuMonitorIOThreadInfo structure so that a subsequent change to modify the iothread info can just generate and pass one. Signed-off-by: John Ferlan --- src/qemu/qemu_driver.c | 26 +++--- 1 file changed, 15 insertions(+), 11

[libvirt] [PATCH 10/11] qemu: Introduce qemuDomainSetIOThreadParams

https://bugzilla.redhat.com/show_bug.cgi?id=1545732 Implement the QEMU driver mechanism in order to set the polling parameters for an IOThread within the bounds specified by the QEMU qapi parameter passing. Based heavily on patches originally posted by Pavel Hrdina , but modified to only handle

[libvirt] [PATCH 04/11] virsh: Add ability to display IOThread stats

Add an --iothread qualifier to domstats and an explanation in the man page. Describe the values in as generic terms as possible allowing each hypervisor to provide a specific algorithm to utilize the values as it sees fit. Signed-off-by: John Ferlan --- tools/virsh-domain-monitor.c | 7 +++

[libvirt] [PATCH 05/11] lib: Introduce virDomainSetIOThreadParams

Create a new API that will allow an adjustment of IOThread polling parameters for the specified IOThread. These parameters will not be saved in the guest XML. Currently the only parameters supported will allow the hypervisor to adjust the parameters used to limit and alter the scope of the polling

[libvirt] [PATCH 02/11] qemu: Split qemuDomainGetIOThreadsLive

Separate out the fetch of the IOThread monitor call into a separate helper so that a subsequent domain statistics change can fetch the raw IOThread data and parse it as it sees fit. Signed-off-by: John Ferlan --- src/qemu/qemu_driver.c | 59 -- 1 file

[libvirt] [PATCH 01/11] qemu: Check for and return IOThread polling values if available

If there are IOThread polling values in the query-iothreads return buffer, then fill them in and set a bool indicating their presence. This will allow for displaying in a domain stats output eventually. Note that the QEMU values are managed a bit differently (as int's stored in int64_t's) than we

[libvirt] [PATCH 07/11] qemu: Alter qemuDomainChgIOThread to take enum instead of bool

Add functions to set the IOThreadInfo param data for the live guest. Based on code originally posted by Pavel Hrdina , but extracted into a separate patch. Note that qapi expects to receive integer parameters rather than unsigned long long or unsigned int's. QEMU does save the value in larger

[libvirt] [PATCH 03/11] qemu: Implement the ability to return IOThread stats
