[libvirt] PATCH: Fix crash after deleting storage vol fails
by Daniel P. Berrange 06 Mar '09

06 Mar '09

After a little debugging on IRC we discovered a problem in the deletion of storage volumes. We were mistakenly calling virStorageVolFree(vol) even if the delete call failed. So the pool got left with a NULL storage volume, and later use of that pool could crash on this.

by Taeho Kang 06 Mar '09

06 Mar '09

Dear all, I am trying to add defined domains to a hypervisor with virDomainDefineXML function. But I keep getting the following error. libvir: Xen XM error : internal error unable to store config file handle I tried using virsh, but it gave the same error. Does anybody know the cause of this error? Thank you in advance, /Taeho

[libvirt] [RFC]: Secure migration
by Chris Lalancette 05 Mar '09

05 Mar '09

All, I've been looking at implementing secure migration for libvirt. I've taken a look at two approaches; I'll outline them, and then tell you which one I think we should do, and why. Note that in the discussion below, I'm talking mostly about the qemu migration protocol; I believe both of the approaches will lend themselves to, say, Xen, but the details will be different. For the sake of the outlines, I'm using three specific terms: "src" is used to refer to the source of the migration, that is, where the VM is running *before* migration begins; "dst" is used to refer to the destination of the migration, that is, where we want the VM to be at the end; and "controller" refers to the controlling program (usually virsh), which can be run on an entirely separate machine. -------------------------------------------------------------------------------- 1) virsh on the controller connects to the src, and initiates the migration command. In turn, this causes the controller to also connect to the dst. Now, during the "Prepare" step on the dst, we setup a qemu container to listen to some port on localhost. Next, the "Perform" step is called on the src machine. This causes an external program to be forked on the src; this external program connects to the dst (using virConnectOpen), then waits for migration data from the qemu instance. As the migration data comes in, it uses a new RPC call (something like "writeMigrationData") to pass the data to the dst. The dst then takes that data, and writes it out to the waiting qemu container. Pros: Uses existing RPC mechanism, so you don't have to open a new port on the destination Cons: There is a "hidden" dependency between the src and dst, which may be difficult for users to get right (more on this below). 2) virsh on the controller connects to the src, and initiates the migration command. In turn, this causes the controller to also connect to the dst. Now, during the "Prepare" step on the dst, we setup a qemu container to listen to some port (call it 1234) on localhost. It also forks an external program (or a thread) to listen for an incoming gnutls connection. Next, the "Perform" step is call on the src machine. This forks an external program (or thread) to listen for incoming data from a localhost migration, do the gnutls handshake with the dst, and dump the data over the gnutls connection to the dst. Pros: Works mostly transparently; the user doesn't have to set anything up different than they do today for "unsecure" migration Cons: Requires opening a new (but still well-known) port in the firewall on the dst side. -------------------------------------------------------------------------------- More about the "hidden" dependencies for 1). There are quite a few examples of where the controller might have access to both machines, but the src libvirtd does not. A few examples below: a) libvirtd is using TLS + the "tls_allowed_dn_list" in /etc/libvirt/libvirtd.conf on the dst machine. They have it configured so that they can access the machine via TLS on the controller machine, but not from the src machine. b) libvirtd is using SASL digest-md5 on the dst machine. When the src machine tries to connect, it needs a name and password to do so, which it doesn't have. (technically, I guess we could proxy that response back to the controller, and have the user fill it there, and then return back to the src, and then the dst, but it seems roundabout) c) libvirtd is using SASL gssapi on the dst machine. When the src machine tries to connect to the dst, it needs to have the right configuration (i.e. /etc/krb5.conf and /etc/sasl2/libvirt.conf need to work), and it also has to get some kind of principal from the kerberos server (but which principal?). Because of the hidden dependency problem, I think solution 2) is actually more viable; yes, it also has a dependency (opening a hole in the firewall), but that can be documented and will work no matter what other authentication you are doing between the controller and src and dst machines. However, I am open to being convinced otherwise. Thoughts? -- Chris Lalancette

[libvirt] [PATCH] Use posix_fallocate() to allocate disk space
by Amit Shah 04 Mar '09

04 Mar '09

Hi, This is an untested patch to make disk allocations faster and non-fragmented. I'm using posix_fallocate() now but relying on glibc really calling fallocate() if it exists for the file system to be the fastest. - This fails build because libutil needs to be added as a dependency? ../src/.libs/libvirt_driver_storage.a(storage_backend_fs.o): In function `virStorageBackendFileSystemVolCreate': /home/amit/src/libvirt/src/storage_backend_fs.c:1023: undefined reference to `safezero' - What's vol->capacity? Why is ftruncate() needed after the call to (current) safewrite()? My assumption is that the user can specify some max. capacity and wish to allocate only a chunk off it at create-time. Is that correct? The best case to get a non-fragmented VM image is to have it allocated completely at create-time with fallocate(). Currently xfs and ext4 support the fallocate() syscall (btrfs will, too, when it's ready). Comments? Amit >From dfe4780f5990571f026e02e6187cb64505c982c1 Mon Sep 17 00:00:00 2001 From: Amit Shah <amit.shah(a)redhat.com> Date: Tue, 24 Feb 2009 16:55:58 +0530 Subject: [PATCH] Use posix_fallocate() to allocate disk space Using posix_fallocate() to allocate disk space and fill it with zeros is faster than writing the zeros block-by-block. Also, for backing file systems that support the fallocate() syscall, this operation will give us a big speed boost. The biggest advantage of using this is the file will not be fragmented for the allocated chunks.

[libvirt] PATCH: Fix libvirtd test cases
by Daniel P. Berrange 04 Mar '09

04 Mar '09

The libvirtd tests have a number of bugs causing them to fail & generally do bad things. They all currently fail on RHEL5 hosts. - daemon-conf - the abs_topbuild_dir env var was not being set correctly so it failed to find config.h. It also broken by changes in stderr debug output from libvirtd. This patch fixes the env var, and changes it to it just looks for the desired error message, not doing a diff across entire of stdout/err. - libvirtd-fail - again fails because it is diffing the whole of stdout/err and coming across warning messages its not expecting. Change it to look for daemon error exit status because that reliably indicates whether it quit as expected on bogus configs - libvirtd-pool - running the QEMU driver which does not exist, just to test virsh's XML generation capabilities. This adds a --print-xml arg to virsh and uses the test:///default driver for testing, so we avoid the QEMU driver & daemon during tests - libvirt-net-persist - again trying to rnu the QEMU driver which does not exist, and its writing config files into the user's home directory. There's no easy fix for this, so I'm killing it off. It can be tested in the separate integration test suite where you can be sure to arrange for correct pre-requisites and safe working environment src/virsh.c | 51 ++++++++++++++++++++++++--------------- tests/Makefile.am | 3 -- tests/daemon-conf | 13 +++------- tests/libvirtd-fail | 9 ++---- tests/libvirtd-net-persist | 58 --------------------------------------------- tests/libvirtd-pool | 41 ++++++------------------------- 6 files changed, 48 insertions(+), 127 deletions(-) Daniel Index: src/virsh.c =================================================================== RCS file: /data/cvs/libvirt/src/virsh.c,v retrieving revision 1.195 diff -u -p -u -p -r1.195 virsh.c --- src/virsh.c 3 Mar 2009 09:59:02 -0000 1.195 +++ src/virsh.c 3 Mar 2009 19:23:01 -0000 @@ -2923,6 +2923,7 @@ cmdPoolCreate(vshControl *ctl, const vsh */ static const vshCmdOptDef opts_pool_X_as[] = { {"name", VSH_OT_DATA, VSH_OFLAG_REQ, gettext_noop("name of the pool")}, + {"print-xml", VSH_OT_BOOL, 0, gettext_noop("print XML document, but don't define/create")}, {"type", VSH_OT_DATA, VSH_OFLAG_REQ, gettext_noop("type of the pool")}, {"source-host", VSH_OT_DATA, 0, gettext_noop("source-host for underlying storage")}, {"source-path", VSH_OT_DATA, 0, gettext_noop("source path for underlying storage")}, @@ -3002,6 +3003,7 @@ cmdPoolCreateAs(vshControl *ctl, const v { virStoragePoolPtr pool; char *xml, *name; + int printXML = vshCommandOptBool(cmd, "print-xml"); if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; @@ -3009,18 +3011,22 @@ cmdPoolCreateAs(vshControl *ctl, const v if (!buildPoolXML(cmd, &name, &xml)) return FALSE; - pool = virStoragePoolCreateXML(ctl->conn, xml, 0); - free (xml); - - if (pool != NULL) { - vshPrint(ctl, _("Pool %s created\n"), name); - virStoragePoolFree(pool); - return TRUE; + if (printXML) { + printf("%s", xml); + free (xml); } else { - vshError(ctl, FALSE, _("Failed to create pool %s"), name); - } + pool = virStoragePoolCreateXML(ctl->conn, xml, 0); + free (xml); - return FALSE; + if (pool != NULL) { + vshPrint(ctl, _("Pool %s created\n"), name); + virStoragePoolFree(pool); + } else { + vshError(ctl, FALSE, _("Failed to create pool %s"), name); + return FALSE; + } + } + return TRUE; } @@ -3085,6 +3091,7 @@ cmdPoolDefineAs(vshControl *ctl, const v { virStoragePoolPtr pool; char *xml, *name; + int printXML = vshCommandOptBool(cmd, "print-xml"); if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; @@ -3092,18 +3099,22 @@ cmdPoolDefineAs(vshControl *ctl, const v if (!buildPoolXML(cmd, &name, &xml)) return FALSE; - pool = virStoragePoolDefineXML(ctl->conn, xml, 0); - free (xml); - - if (pool != NULL) { - vshPrint(ctl, _("Pool %s defined\n"), name); - virStoragePoolFree(pool); - return TRUE; + if (printXML) { + printf("%s", xml); + free (xml); } else { - vshError(ctl, FALSE, _("Failed to define pool %s"), name); - } + pool = virStoragePoolDefineXML(ctl->conn, xml, 0); + free (xml); - return FALSE; + if (pool != NULL) { + vshPrint(ctl, _("Pool %s defined\n"), name); + virStoragePoolFree(pool); + } else { + vshError(ctl, FALSE, _("Failed to define pool %s"), name); + return FALSE; + } + } + return TRUE; } Index: tests/Makefile.am =================================================================== RCS file: /data/cvs/libvirt/tests/Makefile.am,v retrieving revision 1.76 diff -u -p -u -p -r1.76 Makefile.am --- tests/Makefile.am 3 Mar 2009 17:00:18 -0000 1.76 +++ tests/Makefile.am 3 Mar 2009 19:23:01 -0000 @@ -82,7 +82,6 @@ test_scripts += \ define-dev-segfault \ int-overflow \ libvirtd-fail \ - libvirtd-net-persist \ libvirtd-pool \ read-bufsiz \ read-non-seekable \ @@ -127,7 +126,7 @@ TESTS_ENVIRONMENT = \ abs_top_srcdir=`cd '$(top_srcdir)'; pwd` \ abs_builddir=`cd '$(builddir)'; pwd` \ abs_srcdir=`cd '$(srcdir)'; pwd` \ - CONFIG_HEADER='$(abs_top_builddir)/config.h' \ + CONFIG_HEADER="`cd '$(top_builddir)'; pwd`/config.h" \ PATH="$(path_add)$(PATH_SEPARATOR)$$PATH" \ SHELL="$(SHELL)" \ LIBVIRT_DRIVER_DIR="$(abs_top_builddir)/src/.libs" \ Index: tests/daemon-conf =================================================================== RCS file: /data/cvs/libvirt/tests/daemon-conf,v retrieving revision 1.6 diff -u -p -u -p -r1.6 daemon-conf --- tests/daemon-conf 2 Mar 2009 20:01:26 -0000 1.6 +++ tests/daemon-conf 3 Mar 2009 19:23:01 -0000 @@ -52,15 +52,10 @@ while :; do test $i = $n && break - # Filter out some ignorable diagnostics and drop timestamps - sed \ - -e 's/.*: error : //' \ - -e '/^Cannot set group when not running as root$/d' \ - -e '/^libnuma: Warning: .sys not mounted or no numa system/d' \ - err > k && mv k err - - printf '%s\n\n' "remoteReadConfigFile: $f: $param_name: $msg" > expected-err - diff -u expected-err err || fail=1 + # Check that the diagnostic we want appears + grep "$msg" err 1>/dev/null 2>&1 + RET=$?

[libvirt] [ANNOUNCE] New release virtinst 0.400.2
by Cole Robinson 04 Mar '09

04 Mar '09

I'm happy to announce a new virtinst release, version 0.400.2. The release can be downloaded from: http://virt-manager.org/download.html The direct download link is: http://virt-manager.org/download/sources/virtinst/virtinst-0.400.2.tar.gz This release includes: - New virt-clone option --original-xml, allows cloning a guest from an xml file, rather than require an existing, defined guest. - New virt-install option --import, allows creating a guest from an existing disk image, bypassing any OS install phase. - New virt-install option --host-device, for connecting a physical host device to the guest. - Allow specifying 'cache' value via virt-install's --disk options (Ben Kochie) - New virt-install option --nonetworks (John Levon) - Lots of backend cleanups and documentation improvements. Thanks to everyone who has contributed to this release through testing, bug reporting, submitting patches, and otherwise sending in feedback! Thanks, Cole
