Workaround until the libvirtd fix is available
**Save this code as rados_compat.c**
```
#define _GNU_SOURCE
#include <stdio.h>
#include <string.h>
#include <dlfcn.h>
#include <errno.h>
typedef int (*rados_conf_set_fn)(
void *cluster,
const char *option,
const char *value
);
int rados_conf_set(void *cluster, const char *option, const char *value)
{
static rados_conf_set_fn real_rados_conf_set = NULL;
if (option && strcmp(option, "auth_supported") == 0) {
fprintf(stderr,
"[rados-compat] ignoring deprecated option: "
"auth_supported=%s\n",
value ? value : "(null)");
return 0;
}
if (!real_rados_conf_set) {
dlerror();
real_rados_conf_set =
(rados_conf_set_fn)dlsym(RTLD_NEXT, "rados_conf_set");
const char *err = dlerror();
if (err || !real_rados_conf_set) {
fprintf(stderr,
"[rados-compat] dlsym(rados_conf_set) failed: %s\n",
err ? err : "unknown error");
return -EIO;
}
}
return real_rados_conf_set(cluster, option, value);
}
```
**Then compile and install it:**
_gcc -shared -fPIC -O2 -Wall -Wextra -o librados_compat.so rados_compat.c
-ldl
install -o root -g root -m 0755 librados_compat.so
/usr/local/lib/librados_compat.so_
**Preload it into libvirtd:**
_systemctl edit libvirtd_
```
[Service]
Environment="LD_PRELOAD=/usr/local/lib/librados_compat.so"
```
_systemctl daemon-reload
systemctl restart libvirtd
systemctl restart cloudstack-agent_
