xen: parse and generate hpet item in sxpr Recent versions of Xen disable the virtual HPET by default. This is usually more precise because tick policies are not implemented for the HPET in Xen. However, there may be several reasons to control the HPET manually: 1) to test the emulation; 2) because distros may provide the knob while leaving the default to "enabled" for compatibility reasons. This patch provides support for the hpet item in both sexpr and xm formats, and translates it to a <timer> element.

Xen: Fix <clock> handling XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset (hgd24f37b31030 from 2007-04-03), which tracks the offset between the hypervisors clock and the domains RTC, and is persisted by XenD. In combination with localtime=1 this had a bug until XenD-3.4 (hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug manifests, but at least for me in TZ=Europe/Berlin I see the previous offset relative to utc being applied to localtime again, which manifests in an extra hour being added) XenD implements the following variants for clock/@offset: - PV domains don't have a RTC → 'localtime' \| 'utc' - <3.1: no managed domains → 'localtime' \| 'utc' - ≥3.1: the offset is tracked for HV → 'variable' due to the localtime=1 bug → 'localtime' \| 'utc' - ≥3.4: the offset is tracked for HV → 'variable' Current libvirtd still thinks XenD only implements <clock offset='utc'/> and <clock offset='localtime'/>, which is wrong, since the semantic of 'utc' and 'localtime' specifies, that the offset will be reset on domain-restart, while with 'variable' the offset is kept. (keeping the offset over "virsh edit" is important, since otherwise the clock might jump, which confuses certain guest OSs) xendConfigVersion was last incremented to 4 by the xen-folks for xen-3.1.0. I know of no way to reliably detect the version of XenD (user space tools), which may be different from the version of the hypervisor (kernel) version! Because of this only the change from 'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy behaviour of XenD-3.1 until XenD-3.4. For backward compatibility with previous versions of libvirt Xen-HV still accepts 'utc' and 'localtime', but they are returned as 'variable' on the next read-back from Xend to libvirt, since this is what XenD implements: The RTC is NOT reset back to the specified time on next restart, but the previous offset is kept. This behaviour can be turned off by adding the additional attribute adjustment='reset', in which case libvirt will report an error instead of doing the conversion. The attribute can also be used as a shortcut to offset='variable' with basis='...'. With these changes, it is also necessary to adjust the xen tests: "localtime = 0" is always inserted, because otherwise on updates the value is not changed within XenD. adjustment='reset' is inserted for all cases, since they're all < XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent rtc_timeoffset. Some statements change their order because code was moved around. Signed-off-by: Philipp Hahn <hahn@univention.de> 2012-02-08 10:32:34 -06:00			`localtime = 0`
