[libvirt] Anyway to configure multiple boot devices?
by Matty 03 Jun '09

03 Jun '09

I am running a number of KVM guests on a physical machine, and want to configure the hosts to boot from the network if the internal disk isn't bootable. After reading through a number of documents, I came across the following bug report: https://bugzilla.redhat.com/show_bug.cgi?id=472236 According to that document (and the libvirt Domain XML format document), I should be able to configure two boot device statements by adding two boot tags to the domain configuration: <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> <boot dev='network'/> </os> When I attempt to start a guest with this configuration (I added the new line using virsh's edit command), I receive the following error: virsh # start kvmnode2 libvir: QEMU error : internal error Failure while reading monitor startup output: Input/output error error: Failed to start domain kvmnode2 Has anyone bumped into this? I checked the KVM, libvirt and fedora ML archives, but wasn't able to locate a solution to this. I am using Fedora 10 with the latest updates. Thanks for any insight, - Ryan

[libvirt] Upgrade and PCI Passthrough
by Aaron Clausen 03 Jun '09

03 Jun '09

I upgraded my Debian host to KVM 72 and libvirt 0.6.3-4 in the hopes of gaining use of PCI passthrough. I suspect that the upgrade may have gone a bit awry, because when I attempt to enable passthrough, I get the following error: /usr/bin/kvm: invalid option -- '-pcidevice' Is the version of KVM that I installed too old or is something else going on? -- Aaron Clausen mightymartianca(a)gmail.com

[libvirt] PATCH: Misc user mode linux startup bugs
by Daniel P. Berrange 02 Jun '09

02 Jun '09

There's a number of annoying bugs in the user mode linux driver startup code. This patch fixes lots of them. We failed to check umlMonitorCommand for error, leading to a NULL de-reference due to another bug in that function. This patch also checks if 'res' is NULL before de-referenceing it, just in case. In the code for handling inotify delete events, we duplicated alot of the umlShutdownVMDaemon code, but forgot to close the monitor. This patches makes it just call umlShutdownVMDaemon directly. In one place where we spin in a usleep loop, we forgot to increment our retries counter, making it spin forever. Finally, switch to virKillProcess and make the latter also avoids pid==1, since I can't imagine a time where we'd ever want to kill 'init' :-) Daniel diff --git a/src/uml_driver.c b/src/uml_driver.c --- a/src/uml_driver.c +++ b/src/uml_driver.c @@ -166,9 +166,10 @@ umlIdentifyOneChrPTY(virConnectPtr conn, return -1; } requery: - umlMonitorCommand(NULL, driver, dom, cmd, &res); + if (umlMonitorCommand(NULL, driver, dom, cmd, &res) < 0) + return -1; - if (STRPREFIX(res, "pts:")) { + if (res && STRPREFIX(res, "pts:")) { VIR_FREE(def->data.file.path); if ((def->data.file.path = strdup(res + 4)) == NULL) { virReportOOMError(conn); @@ -176,7 +177,7 @@ requery: VIR_FREE(cmd); return -1; } - } else if (STRPREFIX(res, "pts")) { + } else if (!res || STRPREFIX(res, "pts")) { /* It can take a while to startup, so retry for upto 5 seconds */ /* XXX should do this in a better non-blocking @@ -263,19 +264,15 @@ reread: } if (e->mask & IN_DELETE) { + VIR_DEBUG("Got inotify domain shutdown '%s'", name); if (!virDomainIsActive(dom)) { virDomainObjUnlock(dom); continue; } - dom->def->id = -1; - dom->pid = -1; - if (dom->newDef) { - virDomainDefFree(dom->def); - dom->def = dom->newDef; - } - dom->state = VIR_DOMAIN_SHUTOFF; + umlShutdownVMDaemon(NULL, driver, dom); } else if (e->mask & (IN_CREATE | IN_MODIFY)) { + VIR_DEBUG("Got inotify domain startup '%s'", name); if (virDomainIsActive(dom)) { virDomainObjUnlock(dom); continue; @@ -289,11 +286,13 @@ reread: dom->def->id = driver->nextvmid++; dom->state = VIR_DOMAIN_RUNNING; - if (umlOpenMonitor(NULL, driver, dom) < 0) + if (umlOpenMonitor(NULL, driver, dom) < 0) { + VIR_WARN0("Could not open monitor for new domain"); umlShutdownVMDaemon(NULL, driver, dom); - - if (umlIdentifyChrPTY(NULL, driver, dom) < 0) + } else if (umlIdentifyChrPTY(NULL, driver, dom) < 0) { + VIR_WARN0("Could not identify charater devices for new domain"); umlShutdownVMDaemon(NULL, driver, dom); + } } virDomainObjUnlock(dom); } @@ -383,6 +382,7 @@ umlStartup(void) { goto error; } + VIR_INFO("Adding inotify watch on %s", uml_driver->monitorDir); if (inotify_add_watch(uml_driver->inotifyFD, uml_driver->monitorDir, IN_CREATE | IN_MODIFY | IN_DELETE) < 0) { @@ -595,10 +595,11 @@ static int umlOpenMonitor(virConnectPtr if (umlMonitorAddress(conn, driver, vm, &addr) < 0) return -1; + VIR_DEBUG("Dest address for monitor is '%s'", addr.sun_path); restat: if (stat(addr.sun_path, &sb) < 0) { if (errno == ENOENT && - retries < 50) { + retries++ < 50) { usleep(1000 * 100); goto restat; } @@ -612,7 +613,8 @@ restat: } memset(addr.sun_path, 0, sizeof addr.sun_path); - sprintf(addr.sun_path + 1, "%u", getpid()); + sprintf(addr.sun_path + 1, "libvirt-uml-%u", vm->pid); + VIR_DEBUG("Reply address for monitor is '%s'", addr.sun_path+1); if (bind(vm->monitor, (struct sockaddr *)&addr, sizeof addr) < 0) { virReportSystemError(conn, errno, "%s", _("cannot bind socket")); @@ -656,6 +658,8 @@ static int umlMonitorCommand(virConnectP int retlen = 0, ret = 0; struct sockaddr_un addr; unsigned int addrlen; + + VIR_DEBUG("Run command '%s'", cmd); *reply = NULL; @@ -706,6 +710,8 @@ static int umlMonitorCommand(virConnectP } while (res.extra); + VIR_DEBUG("Command reply is '%s'", NULLSTR(retdata)); + *reply = retdata; return ret; @@ -852,12 +881,10 @@ static void umlShutdownVMDaemon(virConne virDomainObjPtr vm) { int ret; - if (!virDomainIsActive(vm) || - vm->pid <= 1) + if (!virDomainIsActive(vm)) return; - - kill(vm->pid, SIGTERM); + virKillProcess(vm->pid, SIGTERM); if (vm->monitor != -1) close(vm->monitor); diff --git a/src/util.c b/src/util.c --- a/src/util.c +++ b/src/util.c @@ -1680,7 +1680,7 @@ char *virGetHostname(void) /* send signal to a single process */ int virKillProcess(pid_t pid, int sig) { - if (pid < 1) { + if (pid <= 1) { errno = ESRCH; return -1; } -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] PATCH: Fix libvirt log initialization to not override environment
by Daniel P. Berrange 02 Jun '09

02 Jun '09

Witht he libvirtd daemon, if you start it up with LIBVIRT_LOG_OUTPUTS or LIBVIRT_LOG_FILTERS set, then it'll initially use these settings for logging, but then when it reads the config file it'll reset all logging and ignore your environment variables. This is rather confusing ! This quick fix makes it honour this env variables, if the config file has not got explicit overrides.

[libvirt] PATCH: Remove all getuid==0 checks from code
by Daniel P. Berrange 02 Jun '09

02 Jun '09

This patch is preparing the way for future work on allowing the libvirtd daemon to run as a less-privileged user ID. The idea is that we will switch from 'root' to 'libvirtd', but use Linux capabilties to keep the handful of higher privileges we need for our work. Thus any code which does a check of 'getuid() == 0' is guarenteed to break [1]. The way this patch approaches this problem, is to change the driver initialization function virStateInitialize() to have it be passed in a 'int privileged' flag from the libvirtd daemon. Each driver is updated to record this flag, and use it for checks where needed. The only real exception is the Xen driver, where we simply check access(2) against the file we need to open. [1] Technically this is already broken on Solaris, since they already change user id qemud/qemud.c | 39 ++++++++++++++++++++++----------------- qemud/qemud.h | 2 ++ src/driver.h | 2 +- src/libvirt.c | 4 ++-- src/libvirt_internal.h | 2 +- src/lxc_driver.c | 25 +++---------------------- src/network_driver.c | 4 ++-- src/node_device_devkit.c | 2 +- src/node_device_hal.c | 2 +- src/qemu_conf.h | 2 ++ src/qemu_driver.c | 37 +++++++++++++++++++------------------ src/remote_internal.c | 2 +- src/storage_driver.c | 6 +++--- src/uml_conf.h | 2 ++ src/uml_driver.c | 18 +++++++++--------- src/xen_internal.c | 2 +- src/xen_unified.c | 2 +- 17 files changed, 73 insertions(+), 80 deletions(-) Daniel diff -r 5e3b5d1f91c2 qemud/qemud.c --- a/qemud/qemud.c Thu May 21 16:21:20 2009 +0100 +++ b/qemud/qemud.c Thu May 21 16:27:16 2009 +0100 @@ -112,8 +112,6 @@ static int unix_sock_ro_mask = 0666;

[libvirt] PATCH: Fix mingw32 build
by Daniel P. Berrange 29 May '09

29 May '09

On Win32/mingw32 the name 'interface' is #defined to the COM_interface struct. Needless to say, libvirt thus fails to build in spectacular ways. This patch does s/interface/iface/ on all variables.

[libvirt] libvirt needs to dynamically support kvm-img and/or qemu-img
by Doug Goldstein 29 May '09

29 May '09

Several distros out there install "kvm-img" when they install KVM and do not install "qemu-img". The following patch checks for kvm-img and qemu-img and does the right thing. I've taken it a step further and made the check a run-time check instead of a build-time check since people are able to remove and install KVM, QEMU and Xen components as they please and as such may invalidate the build-time check. The patch prefers "kvm-img" over "qemu-img" over "qcow-create" since there was a comment that libvirt wanted to support a feature of qemu-img that wasn't present in upstream qemu releases, however the feature is present in kvm-img. The patch adds a new util function called "virFindFileInPath()" which merely searches PATH for the actual location of the binary. It might be worth-while to make some of the other build-time tool checks run-time with that function since it would allow users to get more features just by installing new tools and wouldn't require distros to disable features because they don't want libvirt to be too dependency heavy. -- Doug Goldstein

[libvirt] PATCH: Fix thread safety with HAL driver restart
by Daniel P. Berrange 29 May '09

29 May '09

The restart method of the HAL implementation of node device is not currently threadsafe, because it destroys and creates the entire driver, including its mutexes.

[libvirt] PATCH: Fix double-free in daemon after client connection drop
by Daniel P. Berrange 29 May '09

29 May '09

If a client drops a connection unexpectedly there is a possiblity of a double free in the daemon if using SASL or TLS. This is because there is possibility for poll() on the socket, returns POLLIN and POLLHUP/ERR at the same time. Both the POLLIN and POLLHUP handling code will attempt to use qemudDispatchClientFailure to mark the client as dieing, doing a double free. It is hard to avoid this potential double-invocation of the cleanup function, so it is preferrable to make it safe Daniel diff -rup libvirt-0.6.2.orig/qemud/qemud.c libvirt-0.6.2.new/qemud/qemud.c --- libvirt-0.6.2.orig/qemud/qemud.c 2009-03-13 17:06:16.000000000 +0000 +++ libvirt-0.6.2.new/qemud/qemud.c 2009-05-28 17:58:44.000000000 +0100 @@ -1397,7 +1397,10 @@ static int qemudDispatchServer(struct qe * jobs have finished, then clean it up elsehwere */ void qemudDispatchClientFailure(struct qemud_client *client) { - virEventRemoveHandleImpl(client->watch); + if (client->watch != -1) { + virEventRemoveHandleImpl(client->watch); + client->watch = -1; + } /* Deregister event delivery callback */ if(client->conn) { @@ -1406,12 +1409,21 @@ void qemudDispatchClientFailure(struct q } #if HAVE_SASL - if (client->saslconn) sasl_dispose(&client->saslconn); + if (client->saslconn) { + sasl_dispose(&client->saslconn); + client->saslconn = NULL; + } free(client->saslUsername); + client->saslUsername = NULL; #endif - if (client->tlssession) gnutls_deinit (client->tlssession); - close(client->fd); - client->fd = -1; + if (client->tlssession) { + gnutls_deinit (client->tlssession); + client->tlssession = NULL; + } + if (client->fd != -1) { + close(client->fd); + client->fd = -1; + } } -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

Here's a patch I was asked to post here that attempts to fix libvirt incorrectly specifying g3bw as the machine type when it calls qemu-system-ppc. The renamed machine type is g3beige. I searched for all occurrences of g3bw and replaced it with g3beige.

[libvirt] PATCH: Fix misc bugs in QEMU ARGV -> XML convertor
by Daniel P. Berrange 28 May '09

28 May '09

Having just tried out the QEMU ARGV -> XML convertor on a random set of args posted on the mailing list I found a few bugs. It didn't cope with a -net arg without a vlan=XX option set - this should assume vlan=0 if not set. It didn't cope with quoting of args with spaces in them. It finally did not generate a random UUID or MAC address if omitted.

[libvirt] PATCH: Don't set ifname or script args for QEMU tap devices
by Daniel P. Berrange 28 May '09

28 May '09

When running QEMU with a type=bridge or type=network interface config, we pass a pre-created TAP device file descriptor, eg -net tap,fd=17,script=,vlan=0,ifname=vnet0 The ifname and script args have always been ignored by all QEMU versions we support. Latest QEMU will now error out if they are set. So this patch drops those two redundant options. NB, then are still set for type=ethernet inteface configs, because in that config we're not creating a TAP device. -net tap,fd=17,vlan=0 There is no impact on test cases, because live TAP devices is something that you can exercise in the test cases.

[libvirt] [PATCH 1/2] (Updated & fixed) OpenNebula driver, libvirt-0.6.2
by "Abel Míguez Rodríguez" 27 May '09

27 May '09

Hi all, Here is the One driver & patches for the current git's master commit "9e9527 - Remove stale QEMU pidfiles". [PATCH 1/2] Patch to be applied to libvirt-0.6.2 sources and building files. [PATCH 2/2] Driver source code. Thanks for all the comments about the patches. We waited for the libvirt's release to update the driver's structure to 0.6.2 and apply the improvements. Here is a short list of the main changes applied: - Included driver's files in a different directory "src/opennebula" - Added Capabilities "virCapabilitiesAddGuest" for "x86_64" and "i686" guests and used "one" as hypervisor at "virCapabilitiesAddGuestDomain". - Instead creating a temporal file to send the VM definition we have updated the API we were using to being able to do everything in memory, so making use of "virBuffer" to create the VM definition Template. - Added previously unsupported features to the ONE Template, other types of disks and graphics (vnc,sdl) settings. - Fixed up warnings at compilation and make 'syntax-check' test passed. thanks, Abel Miguez.

[libvirt] libvirtd 0.6.3 - Kernel Panic - 2.6.27-openvz-briullov.1
by Evan Borgstrom 27 May '09

27 May '09

Hi, I have a machine running 4 OpenVZ VE's and am looking at libvirt as a management tool. My machine is a Sun Fire X2250 with 1 CPU and 4GB of RAM running Gentoo. When I start libvirtd the output below appears in the dmesg output and the machine continues to function for about 30s longer before it starts dumping piles of continuous backtrace onto the console. Can I provide anymore info that will help diagnose this problem or should I open a bug about this? Thanks! -Evan [ 426.613841] WARNING: at fs/sysfs/dir.c:463 sysfs_add_one+0x2a/0x36() [ 426.613843] sysfs: duplicate filename 'lo' can not be created [ 426.613845] Modules linked in: ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 xt_state nf_conntrack ipt_REJECT iptable_filter ip_tables simfs vznetdev vzrst vzcpt tun vzdquota vzethdev vzmon vzdev 8021q bridge stp llc [ 426.613859] Pid: 17966, comm: libvirtd Not tainted 2.6.27-openvz- briullov.1-r1-fb3 #1 [ 426.613863] [<c022291e>] warn_slowpath+0x4b/0x6c [ 426.613869] [<c0333d00>] ? vsnprintf+0x233/0x531 [ 426.613874] [<c02294d1>] ? __sysctl_head_next+0x14/0x99 [ 426.613878] [<c032f826>] ? idr_get_empty_slot+0x13c/0x1f0 [ 426.613883] [<c032f9aa>] ? ida_get_new_above+0xd0/0x171 [ 426.613887] [<c028f9ca>] ? find_inode+0x1f/0x5b [ 426.613891] [<c02bbf5c>] ? sysfs_ilookup_test+0x0/0x11 [ 426.613894] [<c028fac5>] ? ifind+0x32/0x71 [ 426.613897] [<c02bc129>] ? sysfs_find_dirent+0x16/0x27 [ 426.613900] [<c02bc2b9>] sysfs_add_one+0x2a/0x36 [ 426.613903] [<c02bc773>] create_dir+0x43/0x72 [ 426.613906] [<c02bc7e9>] sysfs_create_dir+0x47/0x5b [ 426.613909] [<c033028b>] ? kobject_get+0x12/0x17 [ 426.613912] [<c0330390>] kobject_add_internal+0xb2/0x153 [ 426.613915] [<c03304dc>] kobject_add_varg+0x35/0x41 [ 426.613919] [<c033054d>] kobject_add+0x43/0x49 [ 426.613921] [<c03888e8>] device_add+0x7f/0x470 [ 426.613926] [<c027cd9d>] ? __percpu_alloc_mask+0xb6/0xd5 [ 426.613931] [<c023e5e7>] ? ub_slab_charge+0x4c/0x65 [ 426.613935] [<c03330fe>] ? strlcpy+0x17/0x49 [ 426.613938] [<c045a40c>] netdev_register_kobject+0x59/0x5c [ 426.613943] [<c0451afe>] register_netdevice+0x270/0x332 [ 426.613947] [<c0451bf2>] register_netdev+0x32/0x3f [ 426.613950] [<c03ad540>] loopback_net_init+0x34/0x63 [ 426.613955] [<c044d1eb>] setup_net+0x71/0xbb [ 426.613958] [<c044d534>] copy_net_ns+0x3d/0x99 [ 426.613960] [<c023712b>] create_new_namespaces+0x109/0x196 [ 426.613965] [<c0237370>] copy_namespaces+0x62/0x92 [ 426.613967] [<c0221a50>] copy_process+0x8df/0x105a [ 426.613971] [<c02222b6>] do_fork_pid+0xeb/0x25a [ 426.613973] [<c027f8a2>] ? __fput+0x138/0x140 [ 426.613977] [<c0222438>] do_fork+0x13/0x15 [ 426.613980] [<c02023cb>] sys_clone+0x1f/0x21 [ 426.613983] [<c020399e>] syscall_call+0x7/0xb [ 426.613986] [<c04f0000>] ? init_scattered_cpuid_features+0x4f/0x7d [ 426.613992] ======================= [ 426.613994] ---[ end trace 3809b0ba52b812c7 ]--- [ 426.613997] kobject_add_internal failed for lo with -EEXIST, don't try to register things with the same name in the same directory.
