[libvirt] [PATCH for v1.0.5-maint] Fix use of VIR_STRDUP vs strdup
by Doug Goldstein 11 Jun '13

11 Jun '13

Commit 894f784948a93760629de3cb195c69ef4f4b831f broke the v1.0.5-maint branch because VIR_STRDUP() didn't exist in the v1.0.5 release so the resulting build is missing that symbol.

[libvirt] [PATCH] LXC: Allow to input relative path of program for lxc-enter-namespace
by Gao feng 11 Jun '13

User execvp to replace execv, so user can use relative path to exec programs in container. Such as "lxc-enter-namespace domain ls" And the user can still use absolute path to exec programs.

[libvirt] [PATCH] remote: fix dom->id after virDomainCreateWithFlags
by Marek Marczykowski 11 Jun '13

11 Jun '13

The same issue as (already fixed) in virDomainCreate - REMOTE_PROC_DOMAIN_CREATE_WITH_FLAGS doesn't return new domain ID, only -1 on error or 0 on success. Besides this one fix it is more general problem - local domain object ID can desynchronize with the real one, for example in case of another client creates/destroys domain in the meantime. Perhaps virDomainGetID should be called remotely (with all performance implications...)? Or some event-based notification used?

[libvirt] [PATCH] Fix commit 29c1e913e459058c12d02b3f4b767b3dd428a498
by Peter Krempa 10 Jun '13

10 Jun '13

This patch fixes changes done in commit 29c1e913e459058c12d02b3f4b767b3 that was pushed without implementing review feedback. The flag introduced by the patch is changed to VIR_DOMAIN_VCPU_GUEST and documentation makes the difference between regular hotplug and this new functionality more explicit. The virsh options that enable the use of the new flag are changed to "--guest" and the documentation is fixed too. --- include/libvirt/libvirt.h.in | 2 +- src/libvirt.c | 18 +++++++++--------- src/qemu/qemu_driver.c | 8 ++++---- tools/virsh-domain.c | 34 +++++++++++++++++----------------- tools/virsh.pod | 16 ++++++++-------- 5 files changed, 39 insertions(+), 39 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index e057be1..574b970 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -2120,7 +2120,7 @@ typedef enum { /* Additionally, these flags may be bitwise-OR'd in. */ VIR_DOMAIN_VCPU_MAXIMUM = (1 << 2), /* Max rather than current count */ - VIR_DOMAIN_VCPU_AGENT = (1 << 3), /* Use guest-agent based cpu hotplug */ + VIR_DOMAIN_VCPU_GUEST = (1 << 3), /* Modify state of the cpu in the guest */ } virDomainVcpuFlags; int virDomainSetVcpus (virDomainPtr domain, diff --git a/src/libvirt.c b/src/libvirt.c index 820519a..620dbdd 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -8907,10 +8907,10 @@ error: * current virtual CPU limit, which must be less than or equal to the * maximum limit. * - * If @flags includes VIR_DOMAIN_VCPU_AGENT, then a guest agent is used to - * modify the number of processors used by a domain.
