[PATCH v2] ch: Enable hyperv hypervisor
by Praveen K Paladugu 12 Mar '24

12 Mar '24

From: Praveen K Paladugu <prapal(a)linux.microsoft.com> Cloud-Hypervisor is capable of running VMs with kvm or mshv as the hypervisor on Linux Host. Guest to hypevisor ABI with mshv hypervisor is the same as in the case of VIR_DOMAIN_VIRT_HYPERV. So, VIR_DOMAIN_VIRT_HYPERV type will be reused to represent the config with Linux Host and mshv as the hypervisor. While initializing ch driver, check if either of /dev/kvm or /dev/mshv device is present on the host. Before starting ch domains, check if the requested hypervisor device is present on the host. Users can specify hypervisor in ch guests's domain definitions like below: <domain type='kvm'> _or_ <domain type='hyperv'> Signed-off-by: Praveen K Paladugu <prapal(a)linux.microsoft.com> Signed-off-by: Praveen K Paladugu <praveenkpaladugu(a)gmail.com> --- src/ch/ch_conf.c | 2 ++ src/ch/ch_driver.c | 7 +++++++ src/ch/ch_process.c | 35 +++++++++++++++++++++++++++++++++++ 3 files changed, 44 insertions(+) diff --git a/src/ch/ch_conf.c b/src/ch/ch_conf.c index f421af5121..1911ae8f8b 100644 --- a/src/ch/ch_conf.c +++ b/src/ch/ch_conf.c @@ -69,6 +69,8 @@ virCaps *virCHDriverCapsInit(void) virCapabilitiesAddGuestDomain(guest, VIR_DOMAIN_VIRT_KVM, NULL, NULL, 0, NULL); + virCapabilitiesAddGuestDomain(guest, VIR_DOMAIN_VIRT_HYPERV, + NULL, NULL, 0, NULL); return g_steal_pointer(&caps); } diff --git a/src/ch/ch_driver.c b/src/ch/ch_driver.c index 96de5044ac..d6294c76ee 100644 --- a/src/ch/ch_driver.c +++ b/src/ch/ch_driver.c @@ -32,6 +32,7 @@ #include "viraccessapicheck.h" #include "virchrdev.h" #include "virerror.h" +#include "virfile.h" #include "virlog.h" #include "virobject.h" #include "virtypedparam.h" @@ -876,6 +877,12 @@ static int chStateInitialize(bool privileged, return -1; } + if (!(virFileExists("/dev/kvm") || virFileExists("/dev/mshv"))) { + virReportError(VIR_ERR_DEVICE_MISSING, "%s", + _("/dev/kvm and /dev/mshv. ch driver failed to initialize.")); + return VIR_DRV_STATE_INIT_ERROR; + } + ch_driver = g_new0(virCHDriver, 1); if (virMutexInit(&ch_driver->lock) < 0) { diff --git a/src/ch/ch_process.c b/src/ch/ch_process.c index 3bde9d9dcf..640f72a9ca 100644 --- a/src/ch/ch_process.c +++ b/src/ch/ch_process.c @@ -637,6 +637,37 @@ chProcessAddNetworkDevices(virCHDriver *driver, return 0; } +/** + * virCHProcessStartValidate: + * @vm: domain object + * + * Checks done before starting a VM. + * + * Returns 0 on success or -1 in case of error + */ +static int virCHProcessStartValidate(virDomainObj *vm) +{ + if (vm->def->virtType == VIR_DOMAIN_VIRT_KVM) { + VIR_DEBUG("Checking for KVM availability"); + if (!virFileExists("/dev/kvm")) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("Domain requires KVM, but it is not available.

[PATCH v2] storage: Upgrade default qcow2 verion to 1.1
by Abhiram Tilak 12 Mar '24

12 Mar '24

Change the default to modern qcow2 as it's supported by all qemu versions supported by libvirt and in fact 'qemu-img' already defaults to the new format for a long time. Some Unittests require changes to pass, now that version 1.1 is default. Unittests like `qcow2-1.1.argv` may not be relevant anymore, but this patch doesn't affect them.

After seeing a couple of patches in the list, it looks like [PATCH v2] is the usual expected behavior. So, I will proceed with that. Many thanks. Sorry for any inconvenience. ________________________________ From: m kamal <recenum(a)outlook.com> Sent: Monday, March 11, 2024 3:45 PM To: Daniel P.

Also, many apologies for forgetting to at least compile the change. I have read the guidelines before but I forgot. Question: After I amend the commit with the right changes, should I simply call "git publish" again? I tested this in a small repo I made and the behaviour is that "git publish" starts a new email chain with [PATCH v2]. Is this what should happen or is it required for the new PATCH to be a reply to this chain? Cheers, Mostafa ________________________________ From: Daniel P.
