Kvm plugin restart compute nodes after kernel installation but after reboot mcollective agent sometimes does not start, which causes deployment failures. Preliminary tests show that rebooting nodes after pre deployment phase may reduce occurence of this problem.

1. Since some files generated during kernel building are only root writeable, this will cause "permission denied" issue in "make clean" in fuel@opnfv iso building which uses normal user priviledge. Building kernel in another directory than the directory mapped into Docker container can resolve the issue. 2.

This patch contains scripts for running cyclictest through yardstick as part of CI integration for KVMforNFV. The scripts will be triggered to create a docker ubuntu container for running yardstick, configuring the host, launching a guest VM and executing cyclictest through yardstick.

2016-07-21Add the "timers: do not raise softirq unconditionally" temporarilyYunhong Jiang2-8/+29
This patch enable the nohz_full and is important for RT. Bring it back temporarily, while waiting for more work on RT community. Please refer to https://lkml.org/lkml/2015/3/17/783 for more information of the revert. A little rebase needed because it's reverted on old code base. Please notice that we change the rt_mutex_trylock() so that we can get the tvec_base lock there. This is sure to be wrong, and should be fixed cleanly. And that's the major reason the original patch are reverted on the upstream RT linux. Will discuss with upstream on how to achieve the solution.

2016-07-18KVM: nVMX: keep preemption timer enabled during L2 executionPaolo Bonzini1-2/+13
Because the vmcs12 preemption timer is emulated through a separate hrtimer, we can keep on using the preemption timer in the vmcs02 to emulare L1's TSC deadline timer. However, the corresponding bit in the pin-based execution control field must be kept consistent between vmcs01 and vmcs02. On vmentry we copy it into the vmcs02; on vmexit the preemption timer must be disabled in the vmcs01 if a preemption timer vmexit happened while in guest mode. The preemption timer value in the vmcs02 is set by vmx_vcpu_run, so it need not be considered in prepare_vmcs02.

2016-07-18KVM: nVMX: avoid incorrect preemption timer vmexit in nested guestWanpeng Li1-0/+2
The preemption timer for nested VMX is emulated by hrtimer which is started on L2 entry, stopped on L2 exit and evaluated via the check_nested_events hook. However, nested_vmx_exit_handled is always returning true for preemption timer vmexit. Then, the L1 preemption timer vmexit is captured and be treated as a L2 preemption timer vmexit, causing NULL pointer dereferences or worse in the L1 guest's vmexit handler: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [< (null)>] (null) PGD 0 Oops: 0010 [#1] SMP Call Trace: ? kvm_lapic_expired_hv_timer+0x47/0x90 [kvm] handle_preemption_timer+0xe/0x20 [kvm_intel] vmx_handle_exit+0x169/0x15a0 [kvm_intel] ? kvm_arch_vcpu_ioctl_run+0xd5d/0x19d0 [kvm] kvm_arch_vcpu_ioctl_run+0xdee/0x19d0 [kvm] ? kvm_arch_vcpu_ioctl_run+0xd5d/0x19d0 [kvm] ? vcpu_load+0x1c/0x60 [kvm] ? kvm_arch_vcpu_load+0x57/0x260 [kvm] kvm_vcpu_ioctl+0x2d3/0x7c0 [kvm] do_vfs_ioctl+0x96/0x6a0 ? __fget_light+0x2a/0x90 SyS_ioctl+0x79/0x90 do_syscall_64+0x68/0x180 entry_SYSCALL64_slow_path+0x25/0x25 Code: Bad RIP value.

If fail to program hardware preemption timer, we will fallback to hrtimer based method, however, a previous programmed preemption timer miss to cancel in this scenario which results in one hardware preemption timer and one hrtimer emulated tsc deadline timer run simultaneously. So sometimes the target guest deadline tsc is earlier than guest tsc, which leads to the computation in vmx_set_hv_timer can underflow and cause delta_tsc to be set a huge value, then host soft lockup as above. This patch fix it by cancelling the previous programmed preemption timer if there is once we failed to program the new preemption timer and fallback to hrtimer based method.

If the TSC deadline timer is programmed really close to the deadline or even in the past, the computation in vmx_set_hv_timer can underflow and cause delta_tsc to be set to a huge value. This generally results in vmx_set_hv_timer returning -ERANGE, but we can fix it by limiting delta_tsc to be positive or zero.

2016-07-18KVM: x86: support using the vmx preemption timer for tsc deadline timerYunhong Jiang5-1/+100
The VMX preemption timer can be used to virtualize the TSC deadline timer. The VMX preemption timer is armed when the vCPU is running, and a VMExit will happen if the virtual TSC deadline timer expires. When the vCPU thread is blocked because of HLT, KVM will switch to use an hrtimer, and then go back to the VMX preemption timer when the vCPU thread is unblocked. This solution avoids the complex OS's hrtimer system, and the host timer interrupt handling cost, replacing them with a little math (for guest->host TSC and host TSC->preemption timer conversion) and a cheaper VMexit. This benefits latency for isolated pCPUs. [A word about performance... Yunhong reported a 30% reduction in average latency from cyclictest. I made a similar test with tscdeadline_latency from kvm-unit-tests, and measured - ~20 clock cycles loss (out of ~3200, so less than 1% but still statistically significant) in the worst case where the test halts just after programming the TSC deadline timer - ~800 clock cycles gain (25% reduction in latency) in the best case where the test busy waits.

Given that OVS doesn't support Linux 4.4 yet we need to add a patch to the OVS sources so that we can build a 4.4 version of the OVS loadable kernel module that works with the RT Linux 4.4 kernel used in OPNFV. The directory `patches/ovs' contains patches (currently only one) that are applied against the OVS tree. The Fuel build script is modified to apply all of the patches in this directory to the OVS tree. Then a working OVS KLM is created that is then inserted into the RT kernel DEB package so that the end result is an RT kernel that supports OVS.
