[libvirt] [PATCH] Remove VIR_DOMAIN_SHUTDOWN_CRASHED from public API
by Daniel P. Berrange 31 Jul '13

31 Jul '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The VIR_DOMAIN_SHUTDOWN_CRASHED state constant does not appear to be used in the QEMU code anyway. It also doesn't make much (any) sense, since the 'shutdown' state is a transient state between 'running' and 'shutoff' which is only used by the Xen driver. It was added in commit 14e7e0ae8db9843aea80245a3d9e6cf5f2ef720d which post-dates v1.1.0, so is safe to remove before 1.1.1 Signed-off-by: Daniel P.

[libvirt] [PATCH] Rename VIR_DOMAIN_PAUSED_GUEST_PANICKED to VIR_DOMAIN_PAUSED_CRASHED
by Daniel P. Berrange 31 Jul '13

31 Jul '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The VIR_DOMAIN_PAUSED_GUEST_PANICKED constant is badly named, leaking the QEMU event name. Elsewhere in the API we use 'CRASHED' rather than 'PANICKED', and the addition of 'GUEST' is redundant since all events are guest related. Thus rename it to VIR_DOMAIN_PAUSED_CRASHED, which matches with VIR_DOMAIN_RUNNING_CRASHED and VIR_DOMAIN_EVENT_CRASHED. It was added in commit 14e7e0ae8db9843aea80245a3d9e6cf5f2ef720d which post-dates v1.1.0, so is safe to rename before 1.1.1 Signed-off-by: Daniel P.

[libvirt] [PATCH V5] add console support in libxl
by Bamvor Jian Zhang 30 Jul '13

30 Jul '13

this patch introduce the console api in libxl driver for both pv and hvm guest. and import and update the libxlMakeChrdevStr function which was deleted in commit dfa1e1dd. Signed-off-by: Bamvor Jian Zhang <bjzhang(a)suse.com> --- Changes since V4: 1), using proper error instead of VIR_ERR_INTERNAL_ERROR. 2), treat safe as unsupported flags in libxl openConsole api. 3), some format and minor logic changes. Changes since V3: implicity forbit dev_name pass to libxl driver due to only one console supported by libxl. Changes since V2: 1), forbid parallel configure because libxl do not support it 2), only support one serial on libxl driver. 3), also remove console code in libxl driver, AFAICS serial is enough for connecting to libxl console. Changes since V1: 1), add virDomainOpenConsoleEnsureACL 3), remove virReportOOMErrorFull when virAsprintf fail. 4), change size_t for non-nagetive number in libxlDomainOpenConsole size_t i; size_t num = 0; 5), fix for make check (1), replace virAsprintf with VIR_STRDUP in two places (2), delete space. src/libxl/libxl_conf.c | 104 +++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_conf.h | 3 ++ src/libxl/libxl_driver.c | 93 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 200 insertions(+) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 5273a26..827dfdd 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -331,6 +331,92 @@ error: } static int +libxlMakeChrdevStr(virDomainChrDefPtr def, char **buf) +{ + virDomainChrSourceDef srcdef = def->source; + const char *type = virDomainChrTypeToString(srcdef.type); + + if (!type) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + "%s", _("unknown chrdev type")); + return -1; + } + + switch (srcdef.type) { + case VIR_DOMAIN_CHR_TYPE_NULL: + case VIR_DOMAIN_CHR_TYPE_STDIO: + case VIR_DOMAIN_CHR_TYPE_VC: + case VIR_DOMAIN_CHR_TYPE_PTY: + if (VIR_STRDUP(*buf, type) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_FILE: + case VIR_DOMAIN_CHR_TYPE_PIPE: + if (virAsprintf(buf, "%s:%s", type, srcdef.data.file.path) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_DEV: + if (VIR_STRDUP(*buf, srcdef.data.file.path) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_UDP: { + const char *connectHost = srcdef.data.udp.connectHost; + const char *bindHost = srcdef.data.udp.bindHost; + const char *bindService = srcdef.data.udp.bindService; + + if (connectHost == NULL) + connectHost = ""; + if (bindHost == NULL) + bindHost = ""; + if (bindService == NULL) + bindService = "0"; + + if (virAsprintf(buf, "udp:%s:%s@%s:%s", + connectHost, + srcdef.data.udp.connectService, + bindHost, + bindService) < 0) + return -1; + break; + } + + case VIR_DOMAIN_CHR_TYPE_TCP: { + const char *prefix; + + if (srcdef.data.tcp.protocol == VIR_DOMAIN_CHR_TCP_PROTOCOL_TELNET) + prefix = "telnet"; + else + prefix = "tcp"; + + if (virAsprintf(buf, "%s:%s:%s%s", + prefix, + srcdef.data.tcp.host, + srcdef.data.tcp.service, + srcdef.data.tcp.listen ?

From: Peter Krempa <pkrempa(a)redhat.com> https://bugzilla.redhat.com/show_bug.cgi?id=905513 Libssh2 isn't reliable enough to support the libvirt transport using it. The problems include mishandling of "known_hosts" files that may confuse users. --- libvirt.spec.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index a3a831f..6236c08 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -252,7 +252,7 @@ %endif # Enable libssh2 transport for new enough distros -%if 0%{?fedora} >= 17 || 0%{?rhel} >= 6 +%if 0%{?fedora} >= 17 %define with_libssh2 0%{!?_without_libssh2:1} %endif -- 1.8.3.2

[libvirt] [PATCH] spec: Don't mix commands with macro definitions
by Jiri Denemark 30 Jul '13

%build section should first define all required macros and then run commands.

[libvirt] 3rd pass at virt-login-shell for joining an LXC Container
by dwalsh＠redhat.com 30 Jul '13

All comments applied except for comments below. Also additional cleanup of error handling. > You'll need to call virGetUserDirectory() before any fork(), since it > calls code which is not async-signal safe. The reason I did this is I needed to call it after the shell setuid, if I call it earlier it sees the UID=0 and gives me /root. I added a new interface char *virGetUserDirectoryByUID(uid_t uid); Since the original interface does not take a UID. > Hmm, looking at this again, I'm wondering you need to fork() > at all. In virsh we do the double-fork dance, because virsh > is an interactive shell & we don't want to affect other parts > of virsh. > This login shell though is different - its only job is to run > inside the namespace. So can't the main process just enter > the namespace directly ? I think you still need to do the second fork to make sure the /bin/sh PID gets put in the container. Otherwise you will have a process running within the container without a local PID. [PATCH] virt-login-shell joins users into lxc container.
