[libvirt] [PATCH v3 0/6] Fix virConnectRegisterCloseCallback and get rid of global variables
by Marc Hartmayer 14 Nov '19

14 Nov '19

After discussions with Peter and Pavel at the KVM forum, I am now sending a v3 of this series after more than a year... sorry for that long delay! The second patch of this patch series fixes the behavior of virConnectRegisterCloseCallback. The subsequent patches remove the need to have the global variables 'qemuProgram' and 'remoteProgram' in libvirtd.[ch]. They only work in combination with the fixed behavior of virConnectRegisterCloseCallback.

[libvirt] [PATCH] qemu: Warn verbosely if using old loader:nvram pairs
by Michal Privoznik 14 Nov '19

14 Nov '19

There are two ways for specifying loader:nvram pairs: 1) --with-loader-nvram configure option 2) nvram variable in qemu.conf Since we have FW descriptors, using this old style is discouraged, but not as strong as one would expect. Produce more warnings: 1) produce a warning if somebody tries the configure option 2) produce a warning if somebody sets nvram variable and at least on FW descriptor was found The reason for producing warning in case 1) is that package maintainers, who set the configure option in the first place should start moving towards FW descriptors and abandon the configure option. After all, the warning is printed into config output only in this case.

[libvirt] [PATCH] libxl: Fix lock manager lock ordering
by Jim Fehlig 14 Nov '19

14 Nov '19

The ordering of lock manager locks in the libxl driver has a flaw that was uncovered by a migration error path. In the perform phase of migration, the source host calls virDomainLockProcessPause to release the lock before sending the VM to the destination host. If the send fails an attempt is made to reacquire the lock with virDomainLockProcessResume, but that too can fail if the destination host has not finished cleaning up the failed VM and releasing the lock it acquired when starting to receive the VM. This change delays calling virDomainLockProcessResume in libxlDomainStart until the VM is successfully created, but before it is unpaused. A similar approach is used by the qemu driver, avoiding the need to release the lock if VM creation fails. In the migration perform phase, releasing the lock with virDomainLockProcessPause is delayed until the VM is successfully sent to the destination, which avoids reacquiring the lock if the send fails.

[libvirt] [PATCH v2 0/3] use virStringParseYesNo helper
by Mao Zhongyi 14 Nov '19

14 Nov '19

A function virStringParseYesNo was added to convert string 'yes' to true and 'no' to false, so use this helper to replace 'STREQ(.*, \"yes\")' and 'STREQ(.*, \"no\")' as it allows us to drop several repetitive if-then-else string->bool conversion blocks. v2->v1 p1: - ignore the return value of virStringParseYesNo. - update the commit message. [Michal Privoznik] p2: - add the Acked-by tag. p3: - pass return value of helper to rc directly.
