Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Paolo Bonzini 2013-04-02 12:36:43 UTC
We do not support the HPET.  CONFIG_HPET must be removed from default-configs/*-softmmu.mak.

See bug 495851 [Hpet support (HAL timer tests failed SVVP testing)].

Comment 2 Miroslav Rezanina 2013-04-23 09:45:20 UTC
Fixed in qemu-kvm-1.4.0-3.el7.x86_64.rpm

Comment 3 Miroslav Rezanina 2013-09-26 09:32:55 UTC
Fix included in qemu-kvm-1.5.3-7.el7

Comment 5 Qian Guo 2013-11-04 08:44:40 UTC
Reproduced this bug with 
qemu-kvm-1.4.0-1.el7.x86_64

Steps
1. Start a rhel7 guest like this:
# /usr/libexec/qemu-kvm -cpu Penryn -enable-kvm -m 4096 -smp 4,sockets=1,cores=4,threads=1 -name rhel7base -drive file=/home/rhel7base.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,werror=stop,rerror=stop,aio=native -device virtio-blk-pci,drive=drive-virtio-disk0,id=virtio-disk0 -boot menu=on -monitor stdio -spice disable-ticketing,port=5930,seamless-migration=on -vga qxl -global qxl-vga.vram_size=67108864 -device virtio-balloon-pci,id=balloon1 -qmp tcp:0:4446,server,nowait

2. In guest check the available_clocksource:
# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
kvm-clock tsc hpet acpi_pm 

There's hpet that available in guest, so the hpet is enabled by default, the bug is reproduced

Verify this bug with qemu-kvm-1.5.3-11.el7.x86_64

Steps:
1. Start the same guest as above :
# /usr/libexec/qemu-kvm -cpu Penryn -enable-kvm -m 4096 -smp 4,sockets=1,cores=4,threads=1 -name rhel7base -drive file=/home/rhel7base.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,werror=stop,rerror=stop,aio=native -device virtio-blk-pci,drive=drive-virtio-disk0,id=virtio-disk0 -boot menu=on -monitor stdio -spice disable-ticketing,port=5930,seamless-migration=on -vga qxl -global qxl-vga.vram_size=67108864 -device virtio-balloon-pci,id=balloon1 -qmp tcp:0:4446,server,nowait

2. In guest check the available_clocksource:
# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
kvm-clock tsc acpi_pm

There's no hpet.

So according to above, this bug is fixed by qemu-kvm-1.5.3-11.el7.x86_64
