[libvirt] Need review of new vswitch concept info for technical accuracy
by Justin Clift 19 Oct '10

19 Oct '10

Hi all, Working on the "Foundation Concepts" for virtual switches at the moment. Does anyone have time/inclination to check over the concept graphics thus far, for technical accuracy? Especially the "Routing mode" and "Non-routing" mode ones, as I'm not sure if that's the right terminology for them: http://wiki.libvirt.org/page/VirtualNetworking#Routing_mode http://wiki.libvirt.org/page/VirtualNetworking#Non-routing_mode General feedback, thoughts, and suggestions are welcome too of course. :) Regards and best wishes, Justin Clift

[libvirt] [PATCH] esx: Handle non-UTF-8 encoded VMX files
by Matthias Bolte 19 Oct '10

19 Oct '10

ESX(i) uses UTF-8, but a Windows based GSX server writes Windows-1252 encoded VMX files. Add a test case to ensure that libxml2 provides Windows-1252 to UTF-8 conversion. --- This more general patch is a replacement for this patch: https://www.redhat.com/archives/libvir-list/2010-October/msg00516.html src/esx/esx_util.c | 48 +++++++++++++++++++++++++++++++++++++++++++++--- src/esx/esx_util.h | 2 ++ src/esx/esx_vmx.c | 30 ++++++++++++++++++++++++++++++ tests/esxutilstest.c | 42 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 119 insertions(+), 3 deletions(-) diff --git a/src/esx/esx_util.c b/src/esx/esx_util.c index 5fe72fc..24b931f 100644 --- a/src/esx/esx_util.c +++ b/src/esx/esx_util.c @@ -612,9 +612,9 @@ esxUtil_ReformatUuid(const char *input, char *output) unsigned char uuid[VIR_UUID_BUFLEN]; if (virUUIDParse(input, uuid) < 0) { - ESX_VI_ERROR(VIR_ERR_INTERNAL_ERROR, - _("Could not parse UUID from string '%s'"), - input); + ESX_ERROR(VIR_ERR_INTERNAL_ERROR, + _("Could not parse UUID from string '%s'"), + input); return -1; } @@ -819,3 +819,45 @@ esxUtil_EscapeDatastoreItem(const char *string) return escaped2; } + + + +char * +esxUtil_ConvertToUTF8(const char *encoding, const char *string) +{ + char *result = NULL; + xmlCharEncodingHandlerPtr handler; + xmlBufferPtr input; + xmlBufferPtr utf8; + + handler = xmlFindCharEncodingHandler(encoding); + + if (handler == NULL) { + ESX_ERROR(VIR_ERR_INTERNAL_ERROR, + _("libxml2 doesn't handle %s encoding"), encoding); + return NULL; + } + + input = xmlBufferCreateStatic((char *)string, strlen(string)); + utf8 = xmlBufferCreate(); + + if (xmlCharEncInFunc(handler, utf8, input) < 0) { + ESX_ERROR(VIR_ERR_INTERNAL_ERROR, + _("Could not convert from %s to UTF-8 encoding"), encoding); + goto cleanup; + } + + result = strdup((const char *)xmlBufferContent(utf8)); + + if (result == NULL) { + virReportOOMError(); + goto cleanup; + } + + cleanup: + xmlCharEncCloseFunc(handler); + xmlBufferFree(input); + xmlBufferFree(utf8); + + return result; +} diff --git a/src/esx/esx_util.h b/src/esx/esx_util.h index 669a4f2..694e935 100644 --- a/src/esx/esx_util.h +++ b/src/esx/esx_util.h @@ -89,4 +89,6 @@ void esxUtil_ReplaceSpecialWindowsPathChars(char *string); char *esxUtil_EscapeDatastoreItem(const char *string); +char *esxUtil_ConvertToUTF8(const char *encoding, const char *string); + #endif /* __ESX_UTIL_H__ */ diff --git a/src/esx/esx_vmx.c b/src/esx/esx_vmx.c index 7dc8e60..7ec8c0e 100644 --- a/src/esx/esx_vmx.c +++ b/src/esx/esx_vmx.c @@ -868,6 +868,8 @@ esxVMX_ParseConfig(esxVMX_Context *ctx, virCapsPtr caps, const char *vmx, { bool success = false; virConfPtr conf = NULL; + char *encoding = NULL; + char *utf8; virDomainDefPtr def = NULL; long long config_version = 0; long long virtualHW_version = 0; @@ -895,6 +897,33 @@ esxVMX_ParseConfig(esxVMX_Context *ctx, virCapsPtr caps, const char *vmx, return NULL; } + /* vmx:.encoding */ + if (esxUtil_GetConfigString(conf, ".encoding", &encoding, true) < 0) { + goto cleanup; + } + + if (encoding == NULL || STRCASEEQ(encoding, "UTF-8")) { + /* nothing */ + } else { + virConfFree(conf); + conf = NULL; + + utf8 = esxUtil_ConvertToUTF8(encoding, vmx); + + if (utf8 == NULL) { + goto cleanup; + } + + conf = virConfReadMem(utf8, strlen(utf8), VIR_CONF_FLAG_VMX_FORMAT); + + VIR_FREE(utf8); + + if (conf == NULL) { + goto cleanup; + } + } + + /* Allocate domain def */ if (VIR_ALLOC(def) < 0) { virReportOOMError(); return NULL; @@ -1359,6 +1388,7 @@ esxVMX_ParseConfig(esxVMX_Context *ctx, virCapsPtr caps, const char *vmx, } virConfFree(conf); + VIR_FREE(encoding); VIR_FREE(sched_cpu_affinity); VIR_FREE(guestOS); diff --git a/tests/esxutilstest.c b/tests/esxutilstest.c index d4042c2..97e154e 100644 --- a/tests/esxutilstest.c +++ b/tests/esxutilstest.c @@ -280,6 +280,47 @@ testEscapeDatastoreItem(const void *data ATTRIBUTE_UNUSED) +struct testWindows1252ToUTF8 { + const char *windows1252; + const char *utf8; +}; + +static struct testWindows1252ToUTF8 windows1252ToUTF8[] = { + { "normal", "normal" }, + { /* "A€Z" */ "A\200Z", "A\342\202\254Z" }, + { /* "Aä1ö2ü3ß4#5~6!7§8/9%Z" */ "A\3441\3662\3743\3374#5~6!7\2478/9%Z", + "A\303\2441\303\2662\303\2743\303\2374#5~6!7\302\2478/9%Z" }, + { /* "hÀÁÂÃÄÅH" */ "h\300\301\302\303\304\305H", + "h\303\200\303\201\303\202\303\203\303\204\303\205H" }, +}; + +static int +testConvertWindows1252ToUTF8(const void *data ATTRIBUTE_UNUSED) +{ + int i; + char *utf8 = NULL; + + for (i = 0; i < ARRAY_CARDINALITY(windows1252ToUTF8); ++i) { + VIR_FREE(utf8); + + utf8 = esxUtil_ConvertToUTF8("Windows-1252", + windows1252ToUTF8[i].windows1252); + + if (utf8 == NULL) { + return -1; + } + + if (STRNEQ(windows1252ToUTF8[i].utf8, utf8)) { + VIR_FREE(utf8); + return -1; + } + } + + return 0; +} + + + static int mymain(int argc, char **argv) { @@ -312,6 +353,7 @@ mymain(int argc, char **argv) DO_TEST(ParseDatastorePath); DO_TEST(ConvertDateTimeToCalendarTime); DO_TEST(EscapeDatastoreItem); + DO_TEST(ConvertWindows1252ToUTF8); return result == 0 ?

[libvirt] [PATCH v3] introduce VIR_CLOSE to be used rather than close()
by Stefan Berger 19 Oct '10

19 Oct '10

V3: - many small nits addressed V2: - following Eric's suggestions and picking up his code suggestions Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here. There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were. I also dare to declare close() as being deprecated in libvirt code base (HACKING).

[libvirt] [PATCH 0/4] Support auditing of guests
by Daniel P. Berrange 19 Oct '10

19 Oct '10

This patch series introduces basic support for auditing of guest operations. The auditing hooks are primarily done in the libvirtd dispatch layer, because we want to hook all stateful drivers like QEMU, LXC, UML, etc. We don't want to audit the remote driver, VMWare, XenAPI etc which are just plain RPC drivers. There is an exception for auditing of the SELinux label assignment. That has to be done right inside the sVirt code since the neccessary info isn't available in the libvirtd dispatch layer. This patch series focuses on lifecycle operations, but there are quite alot of other things that are desirable to audit in the future, so further patches will likely follow. The last patch is semi-related, it fixes up a major screwup in the linking of the daemon that caused duplicated copies of the code to be linked. This was exposed by the audit work. The patches are a combination of work by myself and Miloslav NB, it should compile and run fine with any reasonably recent audit package, but if you want correctly identified log messages you need audit 2.0.5 Also, audit logs only appear if running libvirtd as root. Non root users don't have permissions to generate audit logs. Daniel

[libvirt] [PATCH] qemu: let qemu group look below /var/lib/libvirt/qemu/
by Eric Blake 18 Oct '10

18 Oct '10

From: Dan Kenigsberg <danken(a)redhat.com> Vdsm needs to communicate with its guest agent via unix domain socket, which qemu creates due to the following domain xml device: <channel type='unix'> <target type='virtio' name='com.redhat.rhevm.vdsm'/> <source mode='bind' path='/var/lib/libvirt/qemu/channels/fcp-xp-1.com.redhat.rhevm.vdsm'/> </channel> The location of the socket below /var/lib/libvirt/qemu/channels makes sense, to humans and selinux policy alike. However, that socket should be accessible to vdsm, too. Due to other (storage) reasons, vdsm is to join the "qemu" group. With this patch, vdsm can look below /var/lib/libvirt/qemu and connect to the socket. The socket itself should be chmod'ed to allow qemu group read/write, but that's for another project.

[libvirt] RFC: automatic setting of ip_forwarding (or not)
by Laine Stump 18 Oct '10

18 Oct '10

Currently libvirt will turn on net.ipv4.ip_forward by writing "1\n" to /proc/sys/net/ipv4/ip_forward whenever a virtual network of with a forward mode of "nat" or "route" is started. This is problematic for two reasons: 1) /etc/sysctl.conf is not updated with this information, so any other process reprocessing /etc/sysctl.conf (with "sysctl -a -p") will potentially turn ip forward back to 0, leaving libvirt-created virtual networks in a non-working state, and 2) it's possible the administrator turned off ip forwarding on purpose for security reasons, and our silently turning it on leaves them mistakenly believing it is still off. We've discussed a few ways of remedying this situation lately, and I thought I should summarize all the mentioned ideas, and take a poll to try and determine which way we should fix this. 1) Leave it as is. The simplest solution, but has the problems outlines above. 2) Turn it on in the same place, but do it by writing net.ipv4.ip_forward = 1 to /etc/sysctl.conf and calling "sysctl -a -p". This gives us the same behavior as currently, but with the advantages that a) our change to the config is documented in /etc/sysctl.conf and b) virtual networked guests won't suddenly have their network fail when some other process runs "sysconfig -a -p". However, it seems rather drastic to be turning this on every time a virtual network is started, especially without alerting the admin that this has been done. 3) Whenever a virtual network that would require ip_forward = 1 to operate properly is started (ie at libvirtd start time, and when a network is newly defined), check if it's currently on, and if not log a warning message, informing the admin that they should turn on ip_forward in sysctl.conf and reload it in order to have properly working networking. This would assure that the admin was informed of the necessity for ip_forward, but eliminate the possibility of two processes fighting over the setting of ip_forward, leaving it up to the admin to make the decision and do the right thing. On the other hand, it would prevent libvirt's networking from "just working" on a new install. 4) Turn ip_forward on during libvirt install. This one doesn't make sense to me, because you don't know at the time of libvirt install whether or not the installation if going to end up with any virtual networks that need forwarding. 5) Make ip_forward a tunable in /etc/libvirt/libvirtd.conf, and set it accordingly every time libvirtd is started. I don't know if this makes sense either - if you have NATed or routed virtual networks, you will need ip_forward=1 for them to work properly, and if you don't have them, you don't care, so it's really redundant. **** I think the important things to accomplish are: 1) Avoid having networking magically stop working when someone else reloads sysctl.conf 2) Make sure that the admin realizes that ip_forward is being turned on (or needs to be turned on). 3) If we're going to turn it on, at least don't do it if it's not needed. 4) Something else we need to consider is the ability to provision a host for proper guest networking purely through the libvirt API, and if we were to stop turning on ip_forward automatically when a network was started, that wouldn't work anymore (unless ip_forward happened to be turned on already). So, what are your opinions? (BTW, the firewall rules added for virtual networks suffer from a similar problem - because they're loaded into the kernel directly with the iptables command, there is no external record of them, and some other process reloading the firewall will flush out all libvirt's rules, leaving the guests with nonworking networking. But that discussion is a bigger one, that probably needs to go outside just libvirt, so I'll avoid that here...)

[libvirt] Suggested schedule for next release
by Daniel Veillard 18 Oct '10

18 Oct '10

Last release was 5 weeks ago so this release cycle will be longuer than usual. There was still a number of patches I wanted to get in for next release, but now it might be time to get ready for next release. I suggest to keep until the end of the week for feature patches but enter the feeze during this week-end. That would lead to a 0.8.5 release by Friday 29, getting back to end-of-month release cycles. I'm wondering a bit if the amount of changes at the API level would not be worth a 0.9.0 release instead, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] Mac OS X: dyld: lazy symbol binding failed
by Mitchell Hashimoto 18 Oct '10

18 Oct '10

Hi, This is a cross-post from libvirt-users since there didn't seem to be anyone there familiar with what is going on and this is a dev issue as well. I'm using the Ruby/FFI libvirt library and getting this consistently on Mac OS X: ruby-1.9.2-p0 > FFI::Libvirt.virInitialize dyld: lazy symbol binding failed: Symbol not found: _virThreadInitialize Referenced from: /usr/local/lib/libvirt.dylib Expected in: flat namespace dyld: Symbol not found: _virThreadInitialize Referenced from: /usr/local/lib/libvirt.dylib Expected in: flat namespace Trace/BPT trap I exported DYLD_PRINT_LIBRARIES and it shows that libvirt.dylib is loaded in the process space, but the above still occurs. When I statically link into a C program it works fine, however. Anyone have any idea what could be causing this? See this archive if you'd like to catch up on what was said in libvirt-users (its not a long thread): https://www.redhat.com/archives/libvirt-users/2010-October/msg00050.html Thanks, Mitchell

[libvirt] KVM Windows guest: add hard drive
by Mihamina Rakotomandimby 16 Oct '10

16 Oct '10

Manao ahoana, Hello, Bonjour, I installed a Windows (XP and 2003) guest using one partition as hard drive. I used: sudo virt-install --connect qemu:///system \ --name win2003-01 \ --ram 1024 \ --keymap=fr \ --disk path=/dev/lvm0/win2003-01 \ --cdrom=/home/mihamina/Windows_2003_Server.iso \ --os-type windows \ --os-variant=win2k3 \ --noapic \ --noacpi \ --network=bridge:br0 \ --accelerate \ --vnc \ --force And this works fine. Really fine. The disk section in the definition: <disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01'/> <target dev='hda' bus='ide'/> </disk> After installation, people asked me to add another hard drive to this installation, and then, I added another "disk" in the definition: <disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01'/> <target dev='hda' bus='ide'/> </disk> <disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01-a'/> <target dev='hdb' bus='ide'/> </disk> I destroyed + undefined + defined + started the VM and the definition is OK (dumpxml), but the Windows guest doesnt see any new hard drive. I already tried with replacing "ide" with "virtio", no new hard drive yet. This is my configuration: mihamina@kvm-lxc-02:~$ dpkg -l | grep "virt" ii kvm 72+dfsg-5~lenny5 Full virtualization on x86 hardware ii libvirt-bin 0.4.6-10 the programs for the libvirt library ii libvirt0 0.4.6-10 library for interfacing with different virtualization systems ii python-libvirt 0.4.6-10 libvirt Python bindings ii virt-manager 0.6.0-6 desktop application for managing virtual machines ii virt-viewer 0.0.3-2 Displaying the graphical console of a virtual machine ii virtinst 0.400.0-7 Programs to create and clone virtual machines How to make, with this, new hard drive recognized by the Windows guest?

[libvirt] [PATCH v2] introduce VIR_CLOSE to be used rather than close()
by Stefan Berger 16 Oct '10

16 Oct '10

V2: - following Eric's suggestions and picking up his code suggestions Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here. There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were. I also dare to declare close() as being deprecated in libvirt code base (HACKING).

[libvirt] [RFC PATCH] virsh: new echo command
by Eric Blake 15 Oct '10

15 Oct '10

* tools/virsh.c (cmdEcho): New command. (commands): Add it. (vshCmdOptType): Add VSH_OT_ARGV. (vshCmddefGetData): Special case new opt flag. (vshCommandOptArgv): New function. --- Not complete yet, but this shows what I'm thinking of. Adding the echo command has two benefits: 1. It will let me add unit tests for the recent virsh command line improvements - echo back arbitrary strings to make sure quoting is as desired. This part works with what I have here, before I ran out of time to finish this today. 2. Make it easier for a user on the command line to conver an arbitrary string into something safe for shell evalution and/or XML usage, by munging the input in a way that it can be reused in the desired context. Not yet implemented; hence the RFC.

[libvirt] [PATCH] introduce VIR_CLOSE to be used rather than close()
by Stefan Berger 15 Oct '10

15 Oct '10

Since bugs due to double-closed filedescriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here. There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were. I also dare to declare close() as being deprecated in libvirt code base (HACKING). :-) Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com> --- HACKING | 11 +++++++++++ src/Makefile.am | 3 ++- src/conf/domain_conf.c | 14 ++++++++------ src/conf/network_conf.c | 9 +++++---- src/conf/nwfilter_conf.c | 17 +++++++++-------- src/conf/storage_conf.c | 9 +++++---- src/conf/storage_encryption_conf.c | 5 +++-- src/util/files.c | 37 +++++++++++++++++++++++++++++++++++++ src/util/files.h | 37 +++++++++++++++++++++++++++++++++++++ 9 files changed, 117 insertions(+), 25 deletions(-) Index: libvirt-acl/src/util/files.c =================================================================== --- /dev/null +++ libvirt-acl/src/util/files.c @@ -0,0 +1,37 @@ +/* + * memory.c: safer file handling + * + * Copyright (C) 2010 IBM Corporation + * Copyright (C) 2010 Stefan Berger + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[libvirt] [PATCH v2] Make sure that filedescriptors are only closed once
by Stefan Berger 15 Oct '10

15 Oct '10

V2: also the path where close() failed needs to be corrected; -> time for a VIR_CLOSE() ? Setting fd=-1 in these places makes sure that the fd is not closed twice later on in 'clean:'. This is of course a recipe for disaster in a multi-threaded system where the filedescriptor can belong to something else right away. At least we have a pattern... (looks like I can close the augeas bug as well...)
