rom loader: make vga+rom loading configurable. · de2aff17

由 Gerd Hoffmann 提交于 10月 26, 2009

The rom_add_vga() and rom_add_option() macros are transformed into
functions.  They look at the new rom_enable_driver_roms variable
and only do something if it is set to non-zero, making vga+option rom
loading runtime option.  pc_init() sets rom_enable_driver_roms to 1.

With this in place we can move the rom loading calls from pc.c to the
individual drivers.

virtio-net: add tap_has_ufo flag to saved state · 0ce0e8f4

由 Mark McLoughlin 提交于 10月 22, 2009

If we tell the guest we support UFO and then migrate to host which
doesn't support it, we will find ourselves in grave difficulties.

Prevent this scenario by adding a flag to virtio-net's savevm format
which indicates whether the device requires host UFO support.

  - add has_ufo uint8_t field for ease of vmstate conversion

Work around dhclient brokenness · 1d41b0c1

由 Anthony Liguori 提交于 10月 22, 2009

With the latest GSO/csum offload patches, any guest using an unpatched version
of dhclient (any Ubuntu guest, for instance), will no longer be able to get
a DHCP address.

dhclient is actually at fault here. It uses AF_PACKET to receive DHCP responses
but does not check auxdata to see if the packet has a valid csum. This causes
it to throw out the DHCP responses it gets from the virtio interface as there
is not a valid checksum.

Fedora has carried a patch to fix their dhclient (it's needed for Xen too) but
this patch has not made it into a release of dhclient. AFAIK, the patch is in
the dhclient CVS but I cannot confirm since their CVS is not public.

This patch, suggested by Rusty, looks for UDP packets (of a normal MTU) and
explicitly adds a checksum to them if they are missing one.

This allows unpatched dhclients to continue to work without needing to update
the guest kernels.

virtio-net: add vnet_hdr support · 3a330134

由 Mark McLoughlin 提交于 10月 22, 2009

With '-netdev tap,id=foo -nic model=virtio,netdev=foo' virtio-net can
detect that its peer (i.e. the tap backend) supports vnet headers
and advertise to the guest that it can send packets with partial
checksums and/or TSO packets.

One complication is that if we're migrating and the source host
supports IFF_VNET_HDR but the destination host doesn't, we can't then
stop the guest from using those features. In this scenario, we just
fail the migration.
