[Xen-devel] HVM SMP linux guest hangs in cpu_idle() with EFLAGS.IF = 1

[Gianni Tedesco <gianni.tedesco@xxxxxxxxxx>]

Hi,

I've spent a few weeks investigating a very reproducible guest-hangs bug
which appears to affect all hypervisors from at least 3.4.2 through 4.0
to unstable.

To reproduce setup an RHEL5.2 guest for kickstart network install
something like this:

vmlinuz ks=nfs:1.2.3.4:ks-rhel52.cfg ksdevice=eth0 console=tty0
        console=ttyS0,9600n8 serial initrd=initrd.img root=/dev/ram0

With a vm profile something like this:

kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 128
name = "RHEL5.2-ks"
vcpus = 2
vif = [ 'type=ioemu,bridge=xenbr0,mac=00:26:b9:87:0e:d3' ]
disk = [ 'phy:/dev/sdb1,hda,w' ]
device_model = '/usr/lib/xen/bin/qemu-dm'

As long as VCPU's > 1 the guest repeatedly hangs after userspace has
started. In all cases hvmctx reports that the kernel is spinning away in
cpu_idle() as if waiting for an interrupt and EFLAGS.IF = 1. If a key is
pressed either on kb or via serial the system unhangs itself. The system
still responds to network traffic (eg. ping) during this time but that
doesn't unhang it.

I have ruled out all the usual suspects, timer modes, vpt_align, guest
kernel clock sources, acpi, hpet, hap and oos. With a little debugging I
was able to show that timer IRQ's from HPET as well as RESCHED IPI's
were still getting delivered during the hangs. Full ctx dump follows.

Help! :)
