[libvirt] [PATCH] Fix DMI uuid parsing.
by Chris Lalancette 30 Jul '10

30 Jul '10

valgrind was complaining that virUUIDParse was depending on an uninitialized value. Indeed it was; virSetHostUUIDStr() didn't initialize the dmiuuid buffer to 0's, meaning that anything after the string read from /sys was uninitialized. Clear out the dmiuuid buffer before use, and make sure to always leave a \0 at the end.

[libvirt] [PATCH] Do not activate boot=on on devices when not using KVM
by Daniel Veillard 30 Jul '10

30 Jul '10

Basically the 'boot=on' boot selection device is something present in KVM but not in upstream QEmu, as a result if we boot a QEmu domain without KVM acceleration we must disable boot=on ... even if the front end kvm binary expose that capability in the help page.

[libvirt] [PATCH] esx: Improve blocked task detection and fix race condition
by Matthias Bolte 30 Jul '10

30 Jul '10

esxVI_WaitForTaskCompletion can take a UUID to lookup the corresponding domain and check if the current task for it is blocked by a question. It calls another function to do this: esxVI_LookupAndHandleVirtualMachineQuestion looks up the VirtualMachine and checks for a question. If there is a question it calls esxVI_HandleVirtualMachineQuestion to handle it. If there was no question or it has been answered the call to esxVI_LookupAndHandleVirtualMachineQuestion returns 0. If any error occurred during the lookup and answering process -1 is returned. The problem with this is, that -1 is also returned when there was no error but the question could not be answered. So esxVI_WaitForTaskCompletion cannot distinguish between this two situations and reports that a question is blocking the task even when there was actually another problem. This inherent problem didn't surface until vSphere 4.1 when you try to define a new domain. The driver tries to lookup the domain that is just in the process of being registered. There seems to be some kind of race condition and the driver manages to issue a lookup command before the ESX server was able to register the domain. This used to work before. Due to the return value problem described above the driver reported a false error message in that case. To solve this esxVI_WaitForTaskCompletion now takes an additional occurrence parameter that describes whether or not to expect the domain to be existent. Also add a new parameter to esxVI_LookupAndHandleVirtualMachineQuestion that allows to distinguish if the call returned -1 because of an actual error or because the question could not be answered. --- src/esx/esx_driver.c | 17 ++++++++++++++- src/esx/esx_vi.c | 53 ++++++++++++++++++++++++++++++++++++------------- src/esx/esx_vi.h | 7 ++++- src/esx/esx_vmx.c | 4 +- 4 files changed, 61 insertions(+), 20 deletions(-) diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index f9affea..eb64556 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -1409,6 +1409,7 @@ esxDomainSuspend(virDomainPtr domain) if (esxVI_SuspendVM_Task(priv->primary, virtualMachine->obj, &task) < 0 || esxVI_WaitForTaskCompletion(priv->primary, task, domain->uuid, + esxVI_Occurrence_RequiredItem, priv->autoAnswer, &taskInfoState) < 0) { goto cleanup;

[libvirt] [PATCH 0/2] build: fix bugs detected by newer gcc
by Eric Blake 30 Jul '10

30 Jul '10

Rawhide's gcc 4.5.0 got smarter in relation to Fedora 13's gcc 4.4.4, and exposed a real bug (introduced by commit ed9c14a7 this January) as well as extra noise that is easy enough to silence. The new warnings looked like: esx/esx_vi_types.c:1231:1: warning: logical 'or' of collectively exhaustive tests is always true [-Wlogical-op] And the esx_vi_types.c case is proof why it is a bad idea to ever stick -Werror in a spec file - upgrade the compiler, and something that previously built silently can now fail to build; in contrast, using -Werror during development is great as it forces you to think about the issue, and in the case of xen, fix a real bug.

CCLD libvirt-qemu.la /usr/bin/ld: cannot open linker script file ./libvirt_qemu.syms: No such file or directory collect2: ld returned 1 exit status make[4]: *** [libvirt-qemu.la] Error 1 make[4]: *** Waiting for unfinished jobs.... make[4]: Leaving directory `/home/jc/rpmbuild/BUILD/libvirt-0.8.2/src' make[3]: *** [all] Error 2 make[3]: Leaving directory `/home/jc/rpmbuild/BUILD/libvirt-0.8.2/src' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/jc/rpmbuild/BUILD/libvirt-0.8.2' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/jc/rpmbuild/BUILD/libvirt-0.8.2' error: Bad exit status from /var/tmp/rpm-tmp.xiUlH6 (%build) In configure.ac, where it's defined as: LIBVIRT_QEMU_SYMBOL_FILE='$(srcdir)/libvirt_qemu.syms' The $srcdir seems to be getting turned into a ".", so that this happens: [jc@host1 libvirt]$ grep -r "libvirt_qemu.syms" . ./gnulib/lib/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./gnulib/tests/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./src/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/xencapsdata/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/xml2sexprdata/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/sexpr2xmldata/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/xmconfigdata/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./tests/confdata/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./include/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./include/libvirt/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./proxy/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms ./python/tests/Makefile:LIBVIRT_QEMU_SYMBOL_FILE = ./libvirt_qemu.syms It looks like the $srcdir needs to be resolved to an absolute path, rather than a relative one, but I have no idea how in autoconf stuff. Any ideas off the top of your head? :) Regards and best wishes, Justin Clift

[libvirt] Failed when client connects to the hypervisor running on Server using TLS
by Xiaoqiang Hu 30 Jul '10

Hi all, Failed when client connects to the hypervisor running on Server using TLS and the details can be seen as follows: I Test Procedures: On server (10.66.92.154) 1. Set up a Certificate Authority (CA) 1.1 # certtool --generate-privkey > cakey.pem 1.2 self-sign cakey.pem by creating a file with the signature details called ca.info containing: cn=10.66.92.154 ca cert_signing_key 1.3 # certtool --generate-self-signed --load-privkey cakey.pem --template ca.info --outfile cacert.pem 2. Create server certificates 2.1 certtool --generate-privkey > serverkey.pem 2.2 sign that key with the CA's private key by first creating a template file called server.info organization=Red Hat cn=10.66.92.154 tls_www_server encryption_key signing_key 2.3 # certtool --generate-certificate --load-privkey serverkey.pem --load-ca-certificate cacert.pem \ --load-ca-privkey cakey.pem --template server.info --outfile servercert.pem 3. Copy CA key and server key to correct directory 3.1 # cp cakey.pem cacert.pem /etc/pki/CA 3.2 # mkdir -p /etc/pki/libvirt/private 3.3 # cp serverkey.pem /etc/pki/libvirt/private 3.4 # cp servercert.pem /etc/pki/libvirt 4. Copy CA key to client(10.66.93.205) into correct directory 4.1 # scp cakey.pem cacert.pem root@10.66.93.205:/etc/pki/CA 5. Turn on libvird monitor listening in /etc/sysconfig/libvirtd -- uncomment LIBVIRTD_ARGS="--listen" 6. Edit /etc/libvirt/libvirtd.conf -- enbale listen_tls = 1 7. # service libvirtd restart 8. # service iptables stop On client (10.66.93.205) 9. Create client certificates 9.1 # certtool --generate-privkey > clientkey.pem 9.2 Act as CA and sign the certificate. Create client.info containing: 9.1 # certtool --generate-privkey > clientkey.pem 9.2 Act as CA and sign the certificate. Create client.info containing: country=GB state=London locality=London organization=Red Hat cn=10.66.93.205 tls_www_client encryption_key signing_key 9.3 # certtool --generate-certificate --load-privkey clientkey.pem --load-ca-certificate /etc/pki/CA/cacert.pem \ --load-ca-privkey /etc/pki/CA/cakey.pem --template client.info --outfile clientcert.pem 10. Copy client key to correct directory 10.1 # mkdir -p /etc/pki/libvirt/private 10.2 # cp clientkey.pem /etc/pki/libvirt/private 10.3 # cp clientcert.pem /etc/pki/libvirt/ 11. Conect to server hypervisor # virsh -c qemu+tls://10.66.92.154/system II Test Result: [root@dhcp-93-205 images]# virsh -c qemu+tls://10.66.92.154/system error: server verification (of our certificate or IP address) failed error: failed to connect to the hypervisor Note: if I Step 9 as above on server and then the client can connect to the hypervisor running on Server using TLS successfully. Regards! Johnson

[libvirt] A error about live migration with --copy-storage-all
by 姚远 30 Jul '10

30 Jul '10

In fedora-13, libvirt is libvirt-0.8.2 and qemu is qemu-kvm-0.12.3. In virsh , the command of "migrate --live fedora-13 qemu+ssh:// 10.1.10.54/system" is going well. but when I use the command of "migrate --live --copy-storage-all fedora-13 qemu+ssh://10.1.10.54/system", it show the error: internal errorqemu: could not open disk image /home/images/fedora-13.img: No such file or directory qemu: could not open disk image /home/images/fedora-13.img: No such file or directory "10.1.10.54" is the ip of destination, and fedora-13 is my VM. I don't know why. My VM "fedora-13" can going well with "virsh start fedora-13" by "/usr/bin/qemu-kvm". Who do live migration with "--copy-storage-all" successfully can help me. What is "--copy-storage-inc migration with non-shared storage with incremental copy (same base image shared between source and destination)"? do that means I also need a shared storage? The document of this I can find out is too less. thank you!
