[libvirt] use virReportOOMError, not VIR_ERR_NO_MEMORY
by Jim Meyering 27 Jan '09

27 Jan '09

I've changed over 200 uses of <some_error_function> with the VIR_ERR_NO_MEMORY flag to call virReportOOMError with whatever "conn"-like argument (if any) was in the original call. I don't claim to have tested these changes (OOM is a pain to simulate, and besides, testing so many failure points would take more infrastructure than we have right now). However, I did automate most of the process. most of the changes were performed automatically via this: perl -0x0 -pi -e \ 's/\w+( ?)$([\w>-]+), *(?:(?:VIR_FROM_NONE|domcode|vm|dom|net|NULL), ?){0,3}VIR_ERR_NO_MEMORY,.*?$;/virReportOOMError$1($2);/sg' \ $(g grep -l VIR_ERR_NO_MEMORY|grep '\.c$'|grep -vF virterror.c) Exceptions: ====================== Exceptions (as noted in ChangeLog) were to add the now-required definitions of VIR_FROM_THIS, as needed, e.g., #define VIR_FROM_THIS VIR_FROM_OPENVZ in openvz-related files. Also, I replaced uses of qparam_report_oom automatically: perl -pi -e 's/qparam_report_oom;/virReportOOMError(NULL);/' \ src/qparams.c and removed the definition of that macro manually. I spotted and manually adjusted one misuse of VIR_ERR_NO_MEMORY: remote_internal.c: fix typo that would mistakenly report OOM * src/remote_internal.c (addrToString): Report VIR_ERR_UNKNOWN_HOST, not VIR_ERR_NO_MEMORY. ctxt in src/conf.c is not usable: perl -pi -e 's/virReportOOMError$ctxt$;/virReportOOMError(NULL);/' \ src/conf.c I manually converted two uses of virSexprError(VIR_ERR_NO_MEMORY in src/sexpr.c. And of course, copyright dates were updated via an emacs write hook. The first iteration involved applying the perl-based xforms more of less file by file, and making sure everything still compiled. Once done, I repeated the process on a new branch, automating as much as possible, and then diff'd the branches. The diff was nearly empty, modulo copyright dates and added VIR_FROM_THIS definitions. I'm posting two small sort-of-different changes here. I'll post this big first one separately. >From 099536470ae2cbe9503ed471d391e403fb2587a4 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 27 Jan 2009 12:20:06 +0100 Subject: [PATCH 1/3] error-reporting calls using VIR_ERR_NO_MEMORY: use virReportOOMError instead * src/uml_conf.c (VIR_FROM_THIS): Define to VIR_FROM_UML. * src/xs_internal.c (VIR_FROM_THIS): Define to VIR_FROM_XEN. * src/xml.c (VIR_FROM_THIS): Define to VIR_FROM_XML. * src/stats_linux.c (VIR_FROM_THIS): Define to VIR_FROM_STATS_LINUX. * src/datatypes.c (VIR_FROM_THIS): Define to VIR_FROM_NONE. * src/lxc_conf.c (VIR_FROM_THIS): Define to VIR_FROM_LXC. * src/libvirt.c (VIR_FROM_THIS): Define to VIR_FROM_NONE. * src/node_device_conf.c (VIR_FROM_THIS): Define to VIR_FROM_NODEDEV. * src/openvz_conf.c (VIR_FROM_THIS): Define to VIR_FROM_OPENVZ. * src/openvz_driver.c (VIR_FROM_THIS): Define to VIR_FROM_OPENVZ. * src/conf.c (VIR_FROM_THIS): Define to VIR_FROM_CONF.

[libvirt] Clock problems with Windows guests and Xen
by Matthew Donovan 27 Jan '09

27 Jan '09

When I start Windows guests with libvirt my clocks are 5 hours off. When I use a Xen configuration file, I can specify an offset (rtc_timeoffset = -18000) to get my clock to sync with the host. Is there a way to do specify this offset in XML with libvirt? Right now, I'm using version 0.4.4 but I downloaded the source for 0.5.1 and it looks like that part of domain_conf.c hasn't changed. Thanks for any help! -matthew

Hi, I have a question about libvirt-qpid. The libvirt-qpid is working for QPID broker? If so, it should be added in "livirt is" section of following pages. http://libvirt.org/ How do you think? (If agreed, I add it.) Thanks Atsushi SAKAI

[libvirt] [PATCH] fix errors in virReportSystemErrorFull
by Jim Meyering 27 Jan '09

27 Jan '09

While looking at removing most of the remaining uses of strerror, I spotted problems in virReportSystemErrorFull. 1) it would leak "combined" 2) that allocated, written-into buffer wasn't even used So, since we'd rather avoid having to allocate at all in the error-reporting path (esp for OOM errors), I've made it automatic. >From 8550ec841b4e19049abc4b5e4a2f8a81d1824055 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 26 Jan 2009 14:59:35 +0100 Subject: [PATCH] fix errors in virReportSystemErrorFull * src/virterror.c (virReportSystemErrorFull): Don't leak "combined".

[libvirt] [PATCH] kvm/virtio: Set IFF_VNET_HDR when setting up tap fds
by Mark McLoughlin 27 Jan '09

27 Jan '09

IFF_VNET_HDR is a tun/tap flag that allows you to send and receive large (i.e. GSO) packets and packets with partial checksums. Setting the flag means that every packet is proceeded by the same header which virtio uses to communicate GSO/csum metadata. By enabling this flag on the tap fds we create, we greatly increase the achievable throughput with virtio_net. However, we need to be careful to only set the flag when a) QEMU has support for this ABI and b) the value of the flag is queryable using the TUNGETIFF ioctl. It's nearly five months since kvm-74 - the first KVM release with this feature - was released. Up until now, we've not added libvirt support because there is no clean way to detect support for this in QEMU at runtime. A brief attempt to add a "info capabilities" monitor command to QEMU floundered. Perfect is the enemy of good enough. Probing the KVM version will suffice for now.
