[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 10631
Summary:
Changeset 10631
- BROKEN: Guest networks fail to come up, netdev=eth1 or eth0. HVM
guests on 64bit hypervisors are untestable since c/s 10352
(see failure.12)
- 64bit UP and SMP guests boot cleanly (but no network)
- 32bit UP guests crash on boot (see failure.15)
- 32bit SMP guests fail to boot (see failure.7)
Test Configuration:
Dell Precision WorkStation 380, Dual Core, 2GB, 3 SATA (Intel VT)
64bit XEN Hypervisor on a RHEL4U2 64bit root (/dev/sda)
32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb)
pae=1, acpi=1, apic=1
kernargs (noapic with >1 VCPU & SMP kernel)
64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc)
pae=1, acpi=1, apic=1
kernargs (noapic with >1 VCPU & SMP kernel)
Boot Tests:
Boot a fully virtualized (HVM) guest to the login prompt
Results are marked Pass|Fail where (n) points to a failure description
Regression Tests:
852 tests (851 ltp tests and one 30 minute user load test)
Tests are marked #Pass/#Fail where (n) points to a failure description

Failures:
1. BUG 666: 32bit UP guest fail ltp gettimeofday02:
"Time is going backwards"
2. HVM guests will not boot after changeset 10319:
"Error: Not an HVM capable platform, we stop creating!"
3. BUG 665: 32bit UP guest crashed during user load test:
"(XEN) Couldn''t alloc shadow page! dom1 count=952, Crash in
shadow.c"
4. BUG 664: 32bit 1CPU & 64bit SMP 2 CPU guests hangs under load:
"ata1: command 0x25 timeout, stat 0x50 host_stat 0x64"
5. BUG 663: 64bit SMP guest report these messages while running:
"(XEN) spurious IRQ irq got=-1"
6. BUG 662: 64bit SMP guest report this message in ltp pth_str01/2/3:
"(XEN) <vlapic_accept_irq>level trig mode repeatedly for vector
252"
7. BUG 661: 32bit SMP guest crashes on boot:
"(XEN) __hvm_bug at vmx.c:2289"
8. BUG 678: 64bit 2CPU SMP guest failed several ltp tests with SEGVs or GPF
"sshd[23654] general protection rip:2a9555d426 rsp:7fbfffd000 error
0"
9. BUG 679: 32bit UP guest panic''d when I ran top on both guests
10. BUG 679: If you boot the 64bit guest first the 32bit guest will not boot
11. DOM0 is getting Kernel Oops and during booting and usually hangs
before fully coming up. If I boot with nosmp passed into xen, it comes
up fine.
12. Guest networks fail to come up (netdev=eth1 or eth0).
13. 32bit and 64bit guests will not start, VCPU get no runtime. On the
domain destroy we crash in vmx_clear_vmcs.
14. 32bit UP guests hang on boot
15. 32bit UP guests crash on boot:
Kernel panic - not syncing: include/linux/smp_lock.h:25:
spin_unlock(kernel/sched.c:c035b5e4) not locked
Kernel panic - not syncing: kernel/sched.c:455:
spin_lock(kernel/sched.c:c03e8120) already locked by kernel/sched.c/2665
