This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. Additional note: Afaik this problem is about RHEL6 Xen HVM guest, using PV-on-HVM drivers. This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. This bug is way too short on details. What's the guest kernel release? What type of guest? (I'm currently assuming Pasi identified it correctly, but would have liked to see it in the original report.) What about the host? I see it's xen-unstable, but what c/s? Does save/restore of this guest work on a RHEL5.5 (5.6-beta) host? What does "throw timeout" mean? i.e. what exactly is the error message. All that said, I have a feeling that I know what the problem is, and I think that we've already got it fixed for 6.1. Did the guest crash on a BUG()? Specifically the BUG in alloc_system_vector(): line 351 of arch/x86/include/asm/desc.h If so, then we should have it fixed, and we can probably even find a way to get you a test kernel to confirm. We don't generally test on xen-unstable ourselves. This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Unfortunately, i still hit this issue with rhel6.1. (In reply to comment #11) > Unfortunately, i still hit this issue with rhel6.1. We're going to need to know a lot more about the test environment and bug then, or there's nothing we can do to try reproducing/fixing it. See comment 5 for a list of questions that are still unanswered. Without details I'll have to close this as insufficient info. I used rhel6 GA for testint. Here is the step to reproduce it: 1. install latest(23300) xen in your machine 2. install rhel6 as guest 3. bootup the guest 4. using xl save dom_id snapshot_file to save guest then you will see the error: [root@vt-snb3 var]# xl save 32 snapshot_1 Saving to snapshot_1 new xl format (info 0x0/0x0/14817) libxl: error: libxl_dom.c:420:libxl__domain_suspend_common_callback guest didn't acknowledge suspend, cancelling request libxl: error: libxl_dom.c:441:libxl__domain_suspend_common_callback guest didn't acknowledge suspend, request cancelled xc: error: Suspend request failed: Internal error xc: error: Domain appears not to have suspended: Internal error libxl: error: libxl_dom.c:519:libxl__domain_suspend_common saving domain: domain did not respond to suspend request: Success xl: fatal error: xl_cmdimpl.c:2376: Unknown error 18446744073709551608: libxl_domain_suspend(ctx, NULL, domid, fd) This issue only reproduce with rhel6 guest, rhel5.5 and rhel5.6 don't have the problem. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
