[PATCH] bhyve: process: improve domain startup error handling
by Roman Bogorodskiy 01 Nov '25

01 Nov '25

After executing the bhyve binary, it might happen that it fails very early due to configuration issues (missing/inaccessible files, incorrect custom args), bugs, etc. In this case it'll look like the domain has started normally, but quickly turned off. Improve that by waiting for the domain's vmm entity to appear in /dev/vmm. Signed-off-by: Roman Bogorodskiy <bogorodskiy(a)gmail.com> --- Ideally, I'd also like to display the errors that the bhyve binary logs in this case. But as I'm doing: virCommandSetErrorFD(cmd, &logfd); I'm not sure if I should read that again from logfd, or are there more optimal ways to do that? src/bhyve/bhyve_process.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/src/bhyve/bhyve_process.c b/src/bhyve/bhyve_process.c index 4fb7e642e1..591c2d1ded 100644 --- a/src/bhyve/bhyve_process.c +++ b/src/bhyve/bhyve_process.c @@ -143,7 +143,12 @@ virBhyveProcessStartImpl(struct _bhyveConn *driver, g_autoptr(virCommand) cmd = NULL; g_autoptr(virCommand) load_cmd = NULL; bhyveDomainObjPrivate *priv = vm->privateData; + g_auto(virBuffer) domain_vmm_path_buf = VIR_BUFFER_INITIALIZER; + g_autofree char *domain_vmm_path = NULL; int ret = -1, rc; + size_t i = 0; + int timeout = 3; + bool vmm_appeared = false; logfile = g_strdup_printf("%s/%s.log", BHYVE_LOG_DIR, vm->def->name); if ((logfd = open(logfile, O_WRONLY | O_APPEND | O_CREAT, @@ -228,6 +233,25 @@ virBhyveProcessStartImpl(struct _bhyveConn *driver, goto cleanup; } + virBufferAsprintf(&domain_vmm_path_buf, "/dev/vmm/%s", vm->def->name); + domain_vmm_path = virBufferContentAndReset(&domain_vmm_path_buf); + + do { + if (virFileExists(domain_vmm_path)) { + vmm_appeared = true; + break; + } + + g_usleep(500000); + } while (!vmm_appeared && ++i < timeout); + + if (!vmm_appeared) { + virReportError(VIR_ERR_INTERNAL_ERROR, + _("Domain %1$s didn't show up in /dev/vmm"), + vm->def->name); + goto cleanup; + } + vm->def->id = vm->pid; virDomainObjSetState(vm, VIR_DOMAIN_RUNNING, reason); priv->mon = bhyveMonitorOpen(vm, driver); -- 2.51.0

[PATCH 00/21] crypto: support multiple parallel certificate identities
by Daniel P. Berrangé 31 Oct '25

31 Oct '25

This series aims to improve the support for post-quantum cryptography in TLS connections by allowing multiple sets of certificates to be loaded. The idea is that during a transition period servers will have a traditional RSA based certificate in parallel with an MLDSA based certificate for PQC, and the right one will be dynamically determined during the TLS handshake. The first 12 patches are trivial cleanups. The next 3 patches fix a potential use-after-free problem The last patches introduce support for multiple certificates. NB, in terms of testing this will require either CentOS Stream 10, or Fedora 43. Most other distros will not support PQC out of the box at this time even if they have new enough gnutls, since they don't make use of the crypto-policies package which is needed to enable PQC by default. Daniel P. Berrangé (21): crypto: remove redundant parameter checking CA certs crypto: add missing free of certs array crypto: replace stat() with access() for credential checks crypto: remove redundant access() checks before loading certs crypto: move check for TLS creds 'dir' property crypto: use g_autofree when loading x509 credentials crypto: remove needless indirection via parent_obj field crypto: move release of DH parameters into TLS creds parent crypto: shorten the endpoint == server check in TLS creds crypto: remove duplication loading x509 CA cert crypto: reduce duplication in handling TLS priority strings crypto: introduce method for reloading TLS creds crypto: introduce a wrapper around gnutls credentials crypto: fix lifecycle handling of gnutls credentials objects crypto: make TLS credentials structs private crypto: deprecate use of external dh-params.pem file crypto: avoid loading the CA certs twice crypto: avoid loading the identity certs twice crypto: expand logic to cope with multiple certificate identities crypto: support upto 5 parallel certificate identities docs: creation of x509 certs compliant with post-quantum crypto crypto/meson.build | 5 +- crypto/tlscreds.c | 77 ++-- crypto/tlscredsanon.c | 62 +-- crypto/tlscredsbox.c | 101 +++++ crypto/tlscredsbox.h | 46 ++ crypto/tlscredspriv.h | 36 +- crypto/tlscredspsk.c | 64 ++- crypto/tlscredsx509.c | 592 +++++++++++++++++--------- crypto/tlssession.c | 139 ++---- crypto/trace-events | 1 + docs/about/deprecated.rst | 9 + docs/system/tls.rst | 134 +++++- include/crypto/tlscreds.h | 26 ++ include/crypto/tlscredsx509.h | 6 + tests/unit/test-crypto-tlscredsx509.c | 8 +- ui/vnc.c | 9 +- 16 files changed, 849 insertions(+), 466 deletions(-) create mode 100644 crypto/tlscredsbox.c create mode 100644 crypto/tlscredsbox.h -- 2.51.1

[PATCH v4 1/3] qemu: support riscv-aia feature for RISC-V KVM
by BillXiang 31 Oct '25

31 Oct '25

From: xiangwencheng <xiangwencheng(a)lanxincomputing.com> riscv-aia feature was introduced in qemu-8.2 to specify the KVM AIA mode. The "riscv-aia" parameter is passed along with -accel in QEMU command-line. 1) "riscv-aia=emul": IMSIC is emulated by hypervisor 2) "riscv-aia=hwaccel": use hardware guest IMSIC 3) "riscv-aia=auto": use the hardware guest IMSICs whenever available otherwise we fallback to software emulation. This patch add the corresponding feature named 'riscv-aia'.
