I read some of the previous posts on this forum, which discussed this particular problem. I tried to use the solution that those posts suggested, but I am still having a problem with my dtrace application running on a heavily loaded system. I have the following lines in my D script, #pragma D option aggsize=8m #pragma D option bufsize=16m #pragma D option dynvarsize=16m #pragma D option aggrate=0

v2 was here: https://www.redhat.com/archives/libguestfs/2018-June/msg00109.html v3: - Added/fixed all suggestions from Nir in previous review. Q: I wasn't sure if we still need the "UnsupportedError" class so I left it in. Q: Does the Unix socket always have the same name? What happens if there's more than one transfer happening? I tested this both ways, and it worked both

These two patches add support for using a Unix domain socket to directly access imageio in the case where imageio is running on the conversion host (usually that means virt-v2v is running on the RHV node and something else -- eg. CFME scripts -- arranges that the RHV node is the same one running imageio). Conversions in the normal case are not affected - they happen over TCP as usual. This was

Old imageio proxy was using Authorization header for GET and PUT requests. Remove unneeded authorization when sending OPTIONS request. Remove unneeded duplicated comments about authorization for old imageio, and replace them with a comment when we set needs_auth. --- v2v/rhv-upload-plugin.py | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) diff --git a/v2v/rhv-upload-plugin.py

This series extract oVirt SDK and imageio code to make it eaiser to follow the code and improve error handing in open() and close(). Tested with virt-v2v master. Changes since v1: - Rebase on merged patches from v1 - Fix regression introduced by "rhv-upload: Fix cleanup after errors" - Remove "rhv-upload: Try to remove disk on timeout" since it cannot succeed - Add more

In the case where virt-v2v runs on the same server as the imageio daemon that we are talking to, it may be possible to optimize access using a Unix domain socket. This is only an optimization. If it fails or if we're not running on the same server it will fall back to the usual HTTPS over TCP connection. --- v2v/rhv-upload-plugin.py | 61 +++++++++++++++++++++++++++++++++++++++++++++++- 1

This series extract oVirt SDK and imageio code to make it eaiser to follow the code and improve error handing in open() and close(). The first small patches can be consider as fixes for downstream. Tested based on libguestfs v1.41.5, since I had trouble building virt-v2v and libguestfs from master. Nir Soffer (18): rhv-upload: Remove unused exception class rhv-upload: Check status more

We can use now ImageioClient to communicate with ovirt-imageio server on oVirt host. Using the client greatly simplifies the plugin, and enables new features like transparent proxy support. The client will use transfer_url if possible, or fall back to proxy_url. Since the client implements the buffer protocol, move to version 2 of the API for more efficient pread(). Another advantage the client

When optimizing the connection using unix socket, we handle these cases: - The local host is not an oVirt host (no /etc/vdsm/vdsm.id). - The local host is an oVirt host, but is not registered with engine. - Creating UnixHTTPConnection() fails. Unlikely and probably a bug in the plugin, but we can recover by using the https connection. The current code handle these cases silently, making it

Hi there, I tried to setup a passwddb with mysql, but it wont connect to my database, even if I patch the driver-mysql.c Here a test program I wrote to check the connection: int main() { MYSQL mysql; mysql_init(&mysql); if (mysql_real_connect(&mysql, NULL, "root", "asd2sdf3", "ccc", 0, "/var/lib/mysql/mysql.sock", 0) == NULL)

Previously we lazily requested the server options in the can_* callbacks. The can_* callbacks are always called by nbdkit straight after open, so this just adds complexity for no benefit. This change simply makes the code always fetch the server options during the open callback. This is — functionally at least — mostly just refactoring. However I also added a useful debug message so we can see
