Hi,
Here is a little series that attempt to fix the issue regarding
xen_platform_pci=0 not been handled.
There are two patches, the first one adds an option to specifies the QEMU
machine that a user wants and we handle the xen_platform_pci=0 case using the
new option.
The new options "qemu_machine_override" will help if one want to try a q35
based device model. Otherwise, it will be used by libxl to switch to the "pc"
machine instead of the "xenfv" one when necessary, as the only difference
between both (since QEMU 1.6) is the presence of the xen-platform pci device.
Regards,
Anthony PERARD (2):
libxl: adding support to use -machine option of QEMU.
libxl: Handle xen_platform_pci=0 case with qemu-xen.

This can be used in the future to switch to a Q35 based device model. It can also be used on a recent QEMU to avoid adding the xen-platform device used to setup PV drivers in the guest. Two possible values for now are "pc" or "xenfv" but there are equivalents and xenfv is the default. A possible future use could be qemu_machine_override="q35" when this machine will be able to start successfully on Xen. When passed to qemu, libxl automatically adds ",accel=xen" to the machine option.

I found that disks/cdrom not works with q35 and old qemu paramters used by libxl. With new qemu parameters works and works also with sata instead ide. Probably next week I'll do libxl patches for initial draft of q35 support, new qemu parameters for disk/cdrom using upstream qemu and sata support. I tried to boot Saucy hvm DomU with q35 and sata but qemu crash on kernel loading, tried with both with and without xen-platform. On attachment the serial kernel logs of both cases. Can you take a look? Thanks for any reply and sorry for my bad english.

I thought we had discussed it and it came out of this: t d0b4d64aadb9f4a90669848de9ef3819050a98cd Author: Matt Wilson <msw@amazon.com> Date: Tue Jan 15 13:21:27 2013 +0000 xen/grant-table: correctly initialize grant table version 1 Commit 85ff6acb075a484780b3d763fdf41596d8fc0970 (xen/granttable: Grant tables V2 implementation) changed the GREFS_PER_GRANT_FRAME macro from a constant to a conditional expression. The expression depends on grant_table_version being appropriately set. Unfortunately, at init time grant_table_version will be 0. The GREFS_PER_GRANT_FRAME conditional expression checks for "grant_table_version == 1", and therefore returns the number of grant references per frame for v2. This causes gnttab_init() to allocate fewer pages for gnttab_list, as a frame can old half the number of v2 entries than v1 entries. After gnttab_resume() is called, grant_table_version is appropriately set. nr_init_grefs will then be miscalculated and gnttab_free_count will hold a value larger than the actual number of free gref entries. If a guest is heavily utilizing improperly initialized v1 grant tables, memory corruption can occur. One common manifestation is corruption of the vmalloc list, resulting in a poisoned pointer derefrence when accessing /proc/meminfo or /proc/vmallocinfo: And the reason is that since the xen-platform-pci is not called we never called 'gnttab_setup' (or rather 'gnttab_init()'). I am not really sure how to fix this right - we don't want to load any of the PV drivers, but at the same time the 'xen_domain()' check is turned 'on' by: xen_hvm_guest_init(). which is OK. But if we add in the PV drivers a check for: if (xen_domain()) { if (xen_hvm_domain() && !xen-platform-pci-init-value)) return -ENODEV; } that means we won't be able to load the drivers in random order. Such as xen-blkfront loaded before xen-platform-pci. But that is OK, those modules have a dependency on that driver (I hope!). Something like this?

I have apply it on top of Linux 3.12.1 and no more "kernel BUG at drivers/xen/grant-table.c:1189!" in linux debug. Also, with the patch, my guest will shutdown (without, something prevent from shuting down complitly). So, this patch is working for me.

And start with the following list ? pc pc-i440fx-1.7 pc-i440fx-1.6 pc-i440fx-1.5 pc-i440fx-1.4 pc-1.3 pc-1.2 pc-1.1 pc-1.0 pc-0.15 pc-0.14 pc-0.13 pc-0.12 pc-0.11 pc-0.10 xenfv I wonder how many of this will work. I suspect most of them. The only down side is that it will be necessary to patch libxl if one want to try, let say q35. If we only keep xenfv and pc in the list, it might be better to just not expose the option to the config file, for now.

So it is probably best to not expose the qemu_machine at all. -- Anthony PERARD ^ permalink raw reply [flat|nested] 23+ messages in thread

In a way I think that's the point -- by allowing the user to specify an arbitrary sting, we are implicitly supporting a gigantic range of things which may work in one release or in one particular configuration and then break in a different one. By making an enum, we bake in the exact ones which we consider to be valid. Also, we've been trying to get away from exposing a bunch of qemu-isms to the user via libxl and the xl config file. What might the *user* be trying to do in specifying this option? We should make sure the interface specifies things the user actually wants, and then use qemu's options to implement that, rather than asking the user to specify qemu stuff directly. -George ^ permalink raw reply [flat|nested] 23+ messages in thread

As I understand it, this is a fix to functionality which should be supported, so doesn't need a freeze exception at this point. -George ^ permalink raw reply [flat|nested] 23+ messages in thread
