Hi all, This is the test report of xen-unstable tree. There are two issues found and one issue got fixed. Version Info: ================================================================xen-changeset: 25334:f8279258e3c9 Dom0: linux.git 3.4.0-rc7+ (commit: 568b445...) ================================================================ New issues(2) =============1. long stop during the guest boot process with qcow image http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1821 2. vcpu-set doesn''t take effect on guest http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1822 Fixed issue(1) =============1. when detaching a VF from hvm guest, "xl dmesg" will show some warning information http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1809 Old issues(9) =============1. [ACPI] System cann''t resume after do suspend http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1707 2. [XL]"xl vcpu-set" causes dom0 crash or panic http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1730 3. [VT-D]fail to detach NIC from guest http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1736 4. Sometimes Xen panic on ia32pae Sandybridge when restore guest http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1747 5. [VT-D] device reset fail when create/destroy guest http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1752 6. RHEL6.2/6.1 guest runs quite slow http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1811 7. after detaching a VF from a guest, shutdown the guest is very slow http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1812 8. cpu weight out of range error when create hvm domU http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1818 9. Poor performance when do guest save/restore and migration with linux 3.1 dom0 http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1784 Thanks, Wu Ronghui(Gabriel)

Or does it just mean that xl vcpu-set 0 4 works where xl vcpu-set domU 4 does not? There''s quite a bit of potentially useful info missing from the bug report, like guest config details, xenstore content etc, http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen has a list of various log files which are often useful to help solve bugs, please do consider including those which seem relevant on future bug reports.

''xl vcpu-set domU 4'' doesn''t work for dumU at all. ''xl vcpu-set'' for dom0 also has a bug. You can use ''xl vcpu-set'' command to decrease vCPU number for dom0; but when you try to increase its number you might meet dom0 panic.

We tested against latest linux.git (already including that commit) as dom0, but found that bug #1730 still exist.
