https://bugzilla.kernel.org/show_bug.cgi?id=115451 Bug ID: 115451 Summary: memset hang on pci device memory using kvm Product: Virtualization Version: unspecified Kernel Version: RHEL - 2.6.18-308.el5 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: gauravs.2010@xxxxxxxxx Regression: No i have host x86 based rhel system [kernel version - 2.6.18-308.el5]. On this I am trying to boot up a debian amd64 image using qemu with kvm. On my virtual os i have a pcimem application, through which I R/W any configured memory on pci devices. Issue is whenever i try to use memset in excess of 156 bytes in my pcimem application to configure any pci device memory, call to memset hangs. However, memcpy work fine in all scenarios. memset works fine if boot my virtual os without kvm. my kvm version is : $/usr/libexec/qemu-kvm --help QEMU PC emulator version 0.9.1 (kvm-83-maint-snapshot-20090205), Copyright (c) 2003-2008 Fabrice Bellard -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
