Patch for RHEL-5 applies fine. Created attachment 355824 [details]
Patch to change PVFB not to select abs. pointer
Attached backported patch.
Committed in 89.11.EL . RPMS are available at http://people.redhat.com/vgoyal/rhel4/ Verification failed on, host: rhel5.5-i386 kernel-xen-2.6.18-233.el5 xen-3.0.3-120.el5 guest: rhel4.8 i386 pv, with kernel updated to 89.32.EL Steps to Reproduce: 1. Boot RHEL-4.8 PV guest, and update the guest kernel to 89.32.EL 2. Restart the guest 3. On host run xenstore-ls /local/domain/0/backend/vkbd Actual results: feature-abs-pointer = "1" Expected results: feature-abs-pointer = "0" Additional info: 1. On the same environment, I start a rhel5u5-32-pv guest and run the same command, also feature-abs-pointer = "1" Additional info: 2. On the same environment, I even update the rhel4.8 guest' kernel to 93.EL, and also get feature-abs-pointer = "1". 3. On the same environment, I even update the rhel5.5 guest kernel-xen to kernel-xen-2.6.18-233, also feature-abs-pointer = "1". Hi, Andrew, do you think this bug has been patched and fixed in rhel4.9(93.EL) ? Hi Binbin, you need to search for "request-abs-pointer". It should be "1" without the patch and "0" or absent with the patch. See bug 492866 comment #11. (See also bug 492866 comment #1 which explains that the original description of the bug was not accurate): > Xenstore node /local/domain/0/backend/vkbd shows whether the backend (host) > offered the feature. To see whether the frontend (guest) accepted it, which is > what you want here, you run > > # xenstore-read /local/domain/$DOMID/device/vkbd/0/request-abs-pointer test steps: host: rhel5.5-i386 and x86_64 kernel-xen-2.6.18-231.el5 xen-3.0.3-120.el5 guest: rhel4.9 pv (by updating rhel4.8 guest kernel to 93.ELxenU) 1. Boot RHEL-4.8 PV guest, and update the guest kernel to 93.ELxenU, reboot 2. create the rhel4.9 pv guest 3. On host run xenstore-read /local/domain/$guestid/device/vkbd/0/request-abs-pointer Reproduce on rhel4.8 pv guest with kernel 89.ELxenU: [HOST]# xenstore-read /local/domain/1/device/vkbd/0/request-abs-pointer 1 Verified on rhel4.9 pv guest with kernel 93.ELxenU: [host]# xenstore-read /local/domain/3/device/vkbd/0/request-abs-pointer xenstore-read: couldn't read path /local/domain/3/device/vkbd/0/request-abs-pointer So set this bug be VERIFIED An advisory has been issued which should help the problem described in this bug report.
